OLFA Perforation Cutter 28 235B

What It Is

The OLFA Perforation Cutter 28 235B is a manual rotary cutter designed for cleanly cutting perforated lines in paper, cardboard, or thin sheet materials—not a lawn mower part. It’s typically used in office, craft, or packaging settings for opening boxes or separating perforated sheets.

Fitment & Compatibility

• Not for lawn mowers: This is not a mower blade, belt, or deck component. It works with any standard OLFA 28mm rotary blade system.
• Check blade size: Compatible only with OLFA 28mm round blades (model 28B series). Does not fit 18mm, 45mm, or larger cutters.
• Handle fit: Fits OLFA RTY-2/G and similar rotary cutters that accept the 28B blade system. Verify your cutter’s blade size before buying.
• Material compatibility: Best for paper, cardstock, and thin plastic (up to ~1mm). Not for fabric, leather, or heavy-duty materials.

Key Things to Know

• No assembly needed: The blade is pre-installed and ready to use. No tools required.
• Safety lock: Includes a blade guard that slides to cover the cutting edge when not in use—always engage it after cutting.
• Durability: OLFA blades are high-carbon steel, offering 3–5x longer life than generic blades before dulling. Sharp enough for hundreds of perforation cuts.
• Common gotcha: The perforation wheel can snag on thick or uneven materials—test on scrap first. Not for cutting continuous lines; designed only for perforation.

Should You Buy It

Buy this if you frequently open boxes with perforated flaps, separate sheets of perforated paper, or need a precise, safe tool for repetitive perforation cuts. Skip it if you need a straight cutter for fabric, thick cardboard, or continuous lines—get a standard OLFA rotary cutter instead.
