Olfa Speed Blade Large Size Utility Knife Replacement Blades (20 pack) LBSP20K

Olfa Speed Blades are exceptionally light and fast, even when cutting thick materials. This is due to the fluorine treatment of the alloy steel blades, which gives them their special black finish. 

The fluorine processing and polished surface dramatically reduce resistance while cutting, saving you time and effort as you work.

This pack of 20 blades comes in a special blade case that can be clipped to your pocket or work belt, giving you one-touch access whenever you need to change blades. Suitable for Olfa large-size (18mm) cutters.
