Craft & Professional Products Visit the Store Craft & Professional Products Visit the Store Review: Best box cutter - Built like a tank. Good value. Super sharp, super professional looking, and I love how the blade tightens down. No way you could accidentally deploy the blade. Review: Reviews are correct - Get one. - Like every guy that works with tools I have at least 12 or so different box knives. Many high end, many highly functional, all heavy duty. And just like others here I will tell you I wished I had got these sooner. I own 2 now. Simple & effective. Love that the blade can be adjusted to any micro length or made long. Love that blade lock is very strong keeping blade steady & secure that it can not slip. These knives take up less space in your tool bag / vest and bright color makes them easy to find. A seven segment blade is included but you will want to buy a pack of their black High Carbon Steel HBB replacement blades. OLFA also sells snap-off 'hook' blades & a wood saw blade that fit this knife. ## Features - RAZOR SHARP 25mm BLADE - Preloaded with HB Extra Heavy-Duty Snap-Off Blade from Japanese tool steel for unmatched sharpness and edge retention.
