## Description

OLFA 25mm Extra Heavy-Duty Utility Knife (H-1) - Multi-Purpose Custom Cutting Depth Utility Knife w/Anti Slip Grip & Snap-Off Blade, Replacement Blades: Any OLFA 25mm Blade - Utility Knives - desertcart.com

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.
Review: Quality utility knife - I saw this on Home Renovision and decided to try it out. Sharp blades easily replaceable. Quality and comfortable to hold.
