## Description

Product Description OLFA 5003 L-1 18mm Ratchet-Lock Heavy-Duty Utility Knife From the Manufacturer Original OLFA Snap-Off Heavy Duty Cutter Features A Contour Durable Handle With A Ratchet-Wheel Blade Locking Mechanism And Unlimited Blade Adjustment. Includes LB Blade.

Review: Great design and easy to snap for a fresh blade! Makes for safe and efficient use. - Really nice box cutter. I did some research before purchasing and lots of folks recommended this. The locking mechanism makes me feel safe about it. Though it might not be as fast to open and shut as one that is spring loaded, I prefer to take the time to secure it when opening and closing. The blades are incredibly sharp, cut through very thick, dense cardboard with ease. Simple and clean design. Nice that you can snap off the blades when ready for a fresh one, and refill when you run out. I'm more inclined to snap off when it's time, than to replace a dull blade with a typical knife. This feels safer and more streamlined for me.
Review: The best utility knife - Whenever I work at home I have this knife on me. It works perfect for 10^6 of things! Bought as replacement to the one I lost (was 10 old and was still perfect!)
