OLFA Cutting Tools NZ: The Complete Guide to Rotary Cutters, Blades, Mats & Rulers
OLFA Cutting Tools NZ: The Complete Guide to Rotary Cutters, Blades, Mats & Rulers
A clean, accurate sewing project begins before the first stitch is made.
If fabric pieces are cut unevenly, pattern edges move during cutting or quilt strips vary by even a few millimetres, those small differences can continue through every seam that follows.
That is why a reliable cutting setup matters.
OLFA created the world’s first rotary cutter in 1979 and helped transform the way quilters, dressmakers and creative makers cut fabric. Instead of lifting the material between two scissor blades, a rotary cutter rolls a circular blade across fabric while it remains supported by the cutting surface.
Direct Sewing stocks a comprehensive range of genuine OLFA cutting tools in New Zealand, including rotary cutters, compatible replacement blades, self-healing cutting mats, frosted quilting rulers, craft knives, safety cutters and precision scissors.
This guide explains how the complete OLFA cutting system works and helps you choose the right tools for quilting, patchwork, dressmaking, appliqué and everyday creative cutting.

The Story Behind OLFA Cutting Tools
OLFA’s history began in Japan with founder Yoshio Okada.
In 1956, Okada developed the world’s first snap-off blade cutter after drawing inspiration from the segmented structure of a chocolate bar and the sharp edges created when glass breaks.
In 1979, he introduced another influential cutting invention: the rotary cutter.
The circular rolling blade gave quilters and makers a faster way to cut fabric into strips, shapes and repeated pieces while keeping the material supported on a flat surface.
OLFA has continued developing coordinated cutters, replacement blades, mats, rulers and specialist tools designed to work together as a cutting system.
The recognisable yellow used across many OLFA products is also intentional. It was selected to represent safety and familiarity, two important considerations when designing exposed-blade hand tools.
Why Use a Rotary Cutter Instead of Fabric Scissors?
Rotary cutters do not replace every pair of sewing scissors. Instead, they solve different cutting problems.
Dressmaking shears remain useful for cutting around large garment patterns, working away from a table or navigating areas where the fabric cannot lie completely flat.
A rotary cutter becomes particularly useful when you need:
- Long, straight fabric strips
- Repeated quilt pieces
- Accurate squares and rectangles
- Clean bias strips
- Curves and appliqué shapes
- Several fabric layers cut together
- Fabric cut without lifting it from the table
The circular blade rolls across the material rather than opening and closing through it. When paired with a stable ruler and suitable cutting mat, this can reduce fabric movement and improve consistency across repeated cuts.
The Complete OLFA Cutting System
A rotary cutter should not be considered in isolation.
The most effective setup contains three core tools:
- A rotary cutter in a size suited to the project
- A self-healing cutting mat large enough to support the cut
- A quilting ruler for measurement, alignment and blade guidance
The cutter provides the sharp rolling blade. The mat protects the table and supports the blade. The ruler establishes the measurement and gives the cutter a firm straight edge to follow.
Removing one part of that system usually reduces accuracy or safety. Cutting directly on an ordinary table can damage both the furniture and blade. Using a standard ruler without sufficient thickness can allow the blade to travel over its edge. Cutting without a guide makes long, consistent strips more difficult.
Which OLFA Rotary Cutter Size Should You Choose?
Rotary cutters are available in several blade diameters because no single size is ideal for every task.
| Blade size | Best suited to | Main advantage | OLFA option |
|---|---|---|---|
| 18 mm | Appliqué, tiny curves, templates, miniatures and detailed craft work | Excellent manoeuvrability around tight shapes | OLFA 18 mm Rotary Cutter |
| 28 mm | Curves, smaller quilt pieces, paper craft and controlled detail cutting | A practical balance between detail and cutting reach | OLFA 28 mm Rotary Cutter |
| 45 mm | Everyday quilting, dressmaking, strips, squares and general fabric cutting | The most versatile all-round blade size | OLFA Deluxe 45 mm Rotary Cutter |
| 60 mm | Thicker fabrics, batting, fleece, leather, long cuts and multiple layers | Greater cutting depth and faster progress across large pieces | OLFA Deluxe 60 mm Rotary Cutter |
OLFA 18 mm Rotary Cutter: Designed for Fine Detail
The OLFA 18 mm Rotary Cutter is the smallest standard rotary cutter in the Direct Sewing collection.
The compact blade can turn more sharply than a larger 45 or 60 mm cutter. This makes it useful when the cutting line contains tight curves or small directional changes.
Choose the 18 mm model for:
- Detailed appliqué pieces
- Miniature patchwork
- Freehand curves
- Small templates
- Paper and creative craft work
It can also follow a ruler for short straight cuts, but it is not the most efficient option for long quilt strips or several layers of fabric.
OLFA 28 mm Rotary Cutter: Curves with More Reach
The OLFA 28 mm Rotary Cutter offers more blade reach than the 18 mm model while remaining easy to manoeuvre.
This makes it particularly useful for curved quilt pieces, garment details, smaller pattern sections and craft projects where a 45 mm cutter feels too large.
The 28 mm cutter also features a quick blade-release system that reduces the number of loose parts handled during replacement.
OLFA 45 mm Rotary Cutters: The Everyday All-Rounders
For most quilters, dressmakers and general sewers, 45 mm is the most useful rotary cutter size.
It is large enough to travel efficiently along a ruler and cut several light fabric layers, but remains manageable around moderate curves and pattern shapes.
Direct Sewing offers several OLFA 45 mm formats because handle style and blade operation can influence comfort.
OLFA Deluxe 45 mm Ergonomic Rotary Cutter
The OLFA Deluxe 45 mm Rotary Cutter uses a curved cushioned handle with a squeeze-action blade mechanism.
Squeezing the handle exposes the blade. Releasing it allows the blade to retract, unless the lock has been intentionally set.
This design is useful for makers who prefer gripping the entire handle rather than operating a small sliding cover with one finger.
OLFA Straight-Handle 45 mm Rotary Cutter
The OLFA Straight-Handle 45 mm Rotary Cutter uses the familiar traditional OLFA format.
It is an uncomplicated option for quilters who prefer a narrow handle and direct manual control over the blade cover.
OLFA Quick-Change 45 mm Rotary Cutters
The OLFA Aqua 45 mm Rotary Cutter and OLFA Pink 45 mm Rotary Cutter use a quick-change blade system.
The contoured handles include finger grooves, while the blade can be released and replaced using a lever system. Both models can be configured for right- or left-handed cutting.
OLFA 60 mm Rotary Cutter: Built for Larger Work
The OLFA Deluxe 60 mm Rotary Cutter is designed for larger projects and deeper cutting.
OLFA rates this model for cutting up to 12 layers of cotton, although actual capacity will depend on the fabric, blade condition, cutting pressure and stability of the layers.
The 60 mm cutter is particularly useful for:
- Quilt batting
- Fleece and wool
- Denim and canvas
- Leather and vinyl
- Long straight garment sections
- Repeated bulk cutting
A large blade does not turn as tightly as an 18 or 28 mm cutter, so it is best chosen for depth and efficiency rather than intricate curves.
Cutting Accurate Fabric Circles
Cutting a smooth circle freehand can be difficult, especially when several identical pieces are required.
The OLFA Compass Rotary Cutter uses an 18 mm circular blade and an adjustable pivot point to cut circles approximately 4 cm to 22 cm in diameter.
It is useful for:
- Circular quilt blocks
- Fabric coasters
- Appliqué circles
- Round bag and pouch components
- Paper and mixed-media projects
The ratchet-style handle allows the cutter to move around the pivot without forcing the wrist to complete one continuous rotation.
Choosing the Correct OLFA Replacement Blade
Rotary blades are consumable cutting components.
Even the best blade will eventually lose performance through normal wear, contact with pins, cutting unsuitable surfaces or repeatedly travelling across the same area of a mat.
Always match the replacement blade diameter to the cutter:
- 18 mm cutters require 18 mm replacement blades
- 28 mm cutters require RB28 blades
- 45 mm cutters use RB45-compatible blades
- 60 mm cutters require RB60 blades
Standard 45 mm Blade
The OLFA RB45 Standard Replacement Blade is the everyday option for compatible 45 mm cutters.
For frequent users, the OLFA 45 mm Replacement Blade 10 Pack keeps multiple spare blades ready for production work, quilting classes or busy sewing rooms.
45 mm Endurance Blade
The OLFA RB45H Endurance Blade is hardened using an additional strengthening process.
OLFA rates it for up to twice as many cuts as its standard 45 mm rotary blade. It is particularly useful for frequent quilters, sewing schools and workrooms where blade changes interrupt productivity.
Decorative Pinking Blade
The OLFA 45 mm Pinking Blade produces a decorative zigzag edge.
It can help reduce raveling on suitable woven fabrics and add decorative detail to paper, felt and craft projects.
Pinking is not a complete substitute for overlocking, binding or another secure seam finish where the project will experience regular washing or heavy wear.
When Should a Rotary Blade Be Replaced?
A worn rotary blade may not look visibly blunt, but its cutting behaviour will change.
Common signs include:
- Skipped threads within the cutting line
- Sections that remain attached after one pass
- The cutter requiring noticeably more downward force
- Fabric being pushed instead of sliced
- Repeatedly needing to cut the same line
- A regular skip caused by a nick in one area of the blade
Do not compensate for a dull blade by applying excessive force. Greater force reduces control and increases the chance of the cutter moving away from the ruler.
Replace the blade and inspect the cutting mat for grooves or damage.
Why a Self-Healing Cutting Mat Matters
A proper cutting mat performs three important jobs:
- It protects the table or workbench
- It provides a blade-friendly surface
- It gives fabric a stable area for measuring and cutting
OLFA self-healing mats use layered surfaces designed to close around shallow cuts rather than remaining permanently open like ordinary plastic or timber.
This helps maintain a smoother cutting surface and can extend blade life.
Self-healing does not mean a mat is indestructible. Heavy pressure, repeated cutting in exactly the same groove, heat, direct sunlight and incorrect storage can permanently distort or damage it.
Choosing the Right Cutting Mat Size
Compact 45 × 30 cm Mat
The OLFA Double-Sided Compact Cutting Mat measures 45 × 30 cm.
It is useful for small sewing spaces, classes, appliqué, paper craft and projects that do not require full garment pieces to lie flat.
One side uses metric measurements and the other uses imperial markings.
18 × 24-Inch Cutting Mat
The OLFA 18 × 24-Inch Cutting Grid Mat provides a practical medium-sized surface for quilt blocks, bags, smaller garment sections and everyday craft work.
24 × 36-Inch Large Cutting Mats
A 24 × 36-inch mat provides significantly more room for fabric preparation and long ruler cuts.
The OLFA Large 24 × 36-Inch Cutting Mat uses an imperial grid, while the OLFA Extra-Thick A1 Cutting Mat provides imperial markings on one side and metric markings on the other.
Modern A1 and A2 Double-Sided Mats
The OLFA A1 Double-Sided Cutting Mat and OLFA A2 Double-Sided Cutting Mat feature brown and apricot working surfaces.
These mats provide an alternative to the traditional green OLFA colour while retaining printed measurement grids, layered construction and a stable cutting surface.
Why Use a Rotating Cutting Mat?
When cutting small quilt blocks or appliqué shapes, makers often rotate the fabric repeatedly to approach each edge safely.
Moving the fabric can disturb its alignment, particularly when several layers or small pieces are being cut together.
The OLFA 12 × 12-Inch Rotating Cutting Mat turns through 360 degrees, allowing the cutting angle to change while the fabric remains in place.
It is particularly useful for:
- Squaring quilt blocks
- Trimming half-square triangles
- Cutting repeated patchwork shapes
- Small paper-piecing projects
- Appliqué and craft work
How to Care for an OLFA Cutting Mat
Correct storage is essential.
- Store the mat completely flat
- Keep it away from heaters and direct sunlight
- Do not leave it inside a hot vehicle
- Avoid ironing directly on the mat
- Do not roll or fold a rigid mat
- Use only cutters and blades suitable for the surface
- Distribute cuts rather than repeatedly using the same narrow groove
Heat can cause permanent warping. Once the surface is distorted, rulers and fabric may no longer sit flat enough for accurate cutting.
OLFA Quilting Rulers
A rotary cutter is only as accurate as the guide it follows.
OLFA quilting rulers use frosted acrylic with black markings designed to remain visible over light, dark and patterned fabrics.
The frosted surface also provides additional grip compared with a completely smooth clear ruler.
Direct Sewing stocks several useful sizes:
6.5 × 6.5-Inch Square Ruler
The OLFA QR-6S 6.5 × 6.5-Inch Quilting Ruler is particularly useful for small blocks, squares, half-square triangles and compact patchwork pieces.
6 × 12-Inch Ruler
The OLFA QR-6x12 Quilting Ruler provides additional reach without occupying as much space as a full 24-inch ruler.
It works well for smaller strips, rectangles, angles and detailed quilt cutting.
6 × 24-Inch Ruler
The OLFA QR-6x24 Quilting Ruler is the most versatile choice for cutting full-width fabric strips.
It includes markings at common quilting increments and angle guides for 15, 30, 45, 60 and 90 degrees.
12.5 × 12.5-Inch Square Ruler
The OLFA QR-12S 12.5 × 12.5-Inch Ruler is useful for squaring larger quilt blocks and working with bigger patchwork units.
How to Use a Rotary Cutter Safely
A rotary cutter contains an extremely sharp exposed blade. Treat it with the same care as any professional cutting tool.
- Place the fabric fully on a suitable self-healing cutting mat.
- Position a proper quilting ruler over the measurement line.
- Keep your fingers entirely on top of the ruler and away from its cutting edge.
- Expose the blade only when you are ready to cut.
- Hold the cutter upright against the ruler rather than leaning it over the ruler edge.
- Roll the cutter away from your body using steady pressure.
- Retract or cover the blade immediately after every cut.
- Lock the cutter before changing blades or storing it.
Never cut towards your hand and never attempt to catch a rotary cutter if it falls.
How to Improve Rotary-Cutting Accuracy
Press the Fabric First
Wrinkles and fold lines prevent fabric from lying evenly against the mat. Press the material before measuring and cutting.
Square the Fabric Edge
Before cutting repeated strips, create one clean reference edge. Every later measurement should be taken from that straight line.
Use the Ruler Markings Consistently
Choose either the ruler measurements or the cutting-mat grid as the main reference. Switching between slightly different references can introduce small variations.
Keep the Cutter Upright
Tilting the cutter can push the blade beneath the ruler or cause it to climb over the edge.
Use Enough Pressure, Not Excessive Pressure
A sharp blade should cut using smooth, controlled downward pressure. If considerable force is required, inspect or replace the blade.
Do Not Cut Across Pins
A pin can chip or nick the rotary blade. Remove all pins from the planned cutting path.
OLFA Craft Knives, Safety Cutters and Precision Scissors
The OLFA collection extends beyond rotary cutting.
Direct Sewing also stocks snap-off blade knives for pattern work, cardboard, leather and workshop cutting, alongside precision scissors and safety cutters.
The complete OLFA range includes:
- Heavy-duty snap-off blade utility knives
- Compact craft knives
- Self-retracting safety knives
- Precision appliqué scissors
- Serrated scissors for difficult materials
- Compatible replacement utility blades
Choose a tool according to the material and cutting action required. A rotary cutter is ideal for flat fabric cutting, while a snap-off knife may be better suited to pattern card, templates, leather or workshop materials.

Frequently Asked Questions
What size OLFA rotary cutter is best for beginners?
A 45 mm rotary cutter is the best all-round starting point for most beginners. It can cut strips, squares, garment pieces and moderate curves without feeling as large as a 60 mm cutter.
What is the difference between a 45 mm and 60 mm rotary cutter?
A 45 mm cutter is more versatile for everyday sewing and quilting. A 60 mm cutter provides greater cutting depth for thicker materials, long straight cuts and multiple fabric layers.
Should I buy an 18 mm or 28 mm rotary cutter?
Choose 18 mm for very tight curves and miniature detail. Choose 28 mm when you want improved manoeuvrability but still need enough blade size for ordinary patchwork pieces and moderate curves.
Can OLFA rotary cutters be used left-handed?
Many OLFA rotary cutters can be configured for either right- or left-handed use by changing the blade orientation. Check the individual product instructions before making the change.
Do I need an OLFA cutting mat?
A self-healing cutting mat is strongly recommended whenever using a rotary cutter. It protects the work surface, supports the blade and helps preserve cutting performance.
What size cutting mat should I buy?
Choose the largest mat that fits your normal workspace and projects. A compact mat is suitable for small crafts, while A1 or 24 × 36-inch mats provide more room for quilting and garment cutting.
What does self-healing cutting mat mean?
A self-healing mat has a layered surface designed to close around shallow cuts. This reduces open grooves and helps provide a smoother surface for future cutting.
Can an OLFA cutting mat be rolled?
Rigid OLFA cutting mats should be stored completely flat unless the specific product instructions state otherwise. Rolling, folding or exposing the mat to heat can cause permanent distortion.
Why is my rotary cutter skipping threads?
The blade may be dull or nicked, two blades may be stuck together, the mat may be damaged, or the cutter may be held at an angle. Check the blade assembly and replace the blade where necessary.
How long does an OLFA rotary blade last?
Blade life varies according to the material, number of layers, cutting pressure, mat condition and whether the blade contacts pins or unsuitable surfaces.
Is the OLFA Endurance blade worth buying?
It is particularly useful for frequent cutting. OLFA rates the Endurance blade for up to twice as many cuts as its standard 45 mm blade.
Which quilting ruler should I buy first?
A 6 × 24-inch ruler is the strongest all-round first choice for cutting full-width strips, binding, borders and larger quilt pieces.
What is a rotating cutting mat used for?
A rotating mat allows the cutting direction to change without repeatedly lifting or repositioning the fabric. It is especially useful for trimming quilt blocks and cutting repeated small shapes.
Can rotary cutters cut paper and leather?
Many OLFA cutters can cut paper, light leather, vinyl and other materials. Consider keeping separate blades for fabric and non-fabric use so your best fabric blade remains clean and sharp.
Where can I buy OLFA cutting tools in New Zealand?
You can shop genuine OLFA cutting tools in New Zealand at Direct Sewing, with online ordering, nationwide delivery and an Auckland superstore at 138 Railside Avenue, Henderson.
Cut More Accurately with OLFA
OLFA did not simply introduce another craft cutter.
The rotary cutter changed how fabric could be measured, supported and cut, particularly for quilting and repeated production work.
Today, the OLFA range operates as a complete system. The cutter provides the rolling blade, the mat protects and supports the work, the ruler controls the measurement, and genuine replacement blades keep the system performing correctly.
A beginner may only need a 45 mm cutter, medium mat and 6 × 24-inch ruler. A dedicated quilter may add a rotating mat, square rulers and smaller 28 mm cutter. A professional workroom may benefit from a large A1 surface, 60 mm cutter and ready supply of replacement blades.
