2 Pieces 45 mm Perforating Rotary Cutter Blades Crochet Edge Skip Stitch Rotary Replacement Blades with Plastic Box for Crafting Sewing Leather Paper Cardstock

What It Is

These are 45 mm perforating rotary cutter blades designed for crafting tasks like cutting leather, paper, and cardstock with a skip-stitch or crochet-edge effect. They are not for lawn mowers—this listing is miscategorized; they are replacement blades for rotary cutters used in sewing, quilting, and papercraft.

Fitment & Compatibility

Before buying, confirm your rotary cutter accepts 45 mm blades (common for mid-size cutters, but not universal). Check the arbor hole size—most 45 mm blades use a 6 mm or 1/4-inch center hole, but measure yours. These are aftermarket blades, so they may not fit all brands (e.g., Olfa, Fiskars, or Cricut) perfectly. For leather or thick cardstock, verify the blade’s cutting depth matches your material stack height. No lawn mower deck or model compatibility applies.

Key Things to Know

• Quality variance: At $6.39 for two, these are budget blades. Expect shorter lifespan and potential dulling faster than name-brand (e.g., Olfa) replacements.
• Installation is simple: Just swap out the old blade in your rotary cutter—no tools needed beyond the cutter’s safety lock. Handle with care; edges are extremely sharp.
• Common gotcha: The “perforating” design creates a dashed cut line, not a continuous slit. For skip-stitch or decorative edges, this is intentional, but it won’t work for straight cuts.
• Plastic box is basic: Included storage case is functional but not heavy-duty—blades may shift during travel.

Should You Buy It

Buy these if you need a cheap, quick replacement for light papercraft or occasional leatherwork and don’t mind swapping blades more often. Skip them if you require precision, long durability, or a continuous cut—invest in a branded 45 mm blade instead. Not suitable for any lawn mower use.
