Precision chisel blades designed for arts, graphics and hobby work — the KB4-F delivers a razor-sharp edge for trimming, chiselling and deburring thin plastics, films, wood and other craft materials. Supplied in a handy pack of five, these blades are produced using OLFA’s multi-step manufacturing process for consistent sharpness and edge retention.
The chisel profile gives excellent control for narrow cuts and cross-cuts, while the carbon tool steel construction balances sharpness with durability. These replacement blades are ideal for both hobbyists and professional users who need a clean, accurate finish on detailed trimming tasks.
Features:
- Chisel-shaped art blade for precise trimming, shaping and deburring of plastics, wood and films.
- High-quality carbon tool steel for superior edge retention and finish.
- Pack of 5 replacement blades — convenient spare supply for frequent users.
- Tool-free blade change when used with compatible OLFA art knives (AK-4, AK-1/5B).
- Compact packaging for safe storage and transport.
Tip: Use a self-healing cutting mat and hold the blade at a low angle for cleaner chisel cuts; always store spare blades in their plastic case and replace blades when you notice burr or drag to avoid material damage.
These KB4-F blades are a matched replacement for OLFA precision art knives and are commonly used in modelmaking, sign trimming, graphic art and precision hobby tasks. Keep away from moisture to reduce corrosion risk and handle blades with care — carbon tool steel can be sharpened but should be replaced when worn.
