AMASEWART 45mm Crochet Edge Rotary Cutter Blades, Skip Stitch Rotary Blades Fits Fiskars Olfa, Perforating Rotary Replacement Blade, Pack of 6

What It Is

These are 45mm skip-stitch (perforating) rotary blades designed for fabric cutting, not lawn mowing. They replace blades in Fiskars, Olfa, and similar rotary cutters used in quilting, sewing, and crafting to create perforated edges for decorative cuts or tear-away seams.

Fitment & Compatibility

• Not for lawn mowers – despite the product category, these are strictly for handheld fabric rotary cutters. Do not attempt to use on any mower deck.
• Check blade arbor hole size: Most Fiskars and Olfa rotary cutters use a standard 45mm blade with a 7mm center hole. Measure your current blade’s diameter and hole.
• Skip-stitch specific: Only works if your cutter accepts perforating blades (some models have a separate blade holder or spacer for skip-stitch). Standard straight-cut blades will not interchange without adjusting the cutter’s blade guard.
• Pack of 6: Good for multiple cutter changes or sharing between machines.

Key Things to Know

• Not sharp like standard blades – skip-stitch blades have gaps, so they cut perforations, not clean lines. Do not expect a smooth straight cut.
• Installation is easy – remove the cutter’s retaining screw, swap blades, and re-tighten. No tools beyond the cutter’s own screwdriver (if included).
• Fits most 45mm cutters – works with Fiskars 45mm, Olfa 45mm, and many generic rotary cutters, but double-check the hole size (7mm is standard; some older models use 5mm or 6mm holes).
• Durability is average – skip-stitch blades dull faster than straight-edge blades because of the interrupted cutting edge. Expect to replace every 2-4 projects with heavy use.

Should You Buy It

If you need a budget-friendly pack of skip-stitch blades for a 45mm Fiskars or Olfa rotary cutter and you’re doing fabric perforation or decorative cutting, these work fine for the price. Avoid if you need straight cuts, or if your cutter uses a non-standard hole size. Not for lawn equipment—double-check your intended use.
