    I have had snap off knives before, the cheap disposable kind but these are truly another level. Find I am grabbing this instead of my utility knife due to the way it works. No need to flip out the knife or replace blades. Just click it to loosen and retract. Only a small bit of blade is going to dull vs having to flip the blade in those utility knives and then throw the whole blade away.

    The design of the knife is very good, with a secure lock mechanism, but what I don't like is the handle. It is very shiny and smooth, and you can't get a good grip on it. But I can fix that because I like it, and also is made in Japan instead of China.

    First of all, I'm just a homeowner that cuts up and recycles the card board from the boxes I receive. I do use a
    box cutter often. I recently bought Home Depot's Husky brand cutter for $3 more. It was poor quality and design; hard to use and kept coming apart; I returned it. This OLFA cutter is great quality, easy to use and shows the quality difference of being made in Japan instead of China. It's a winner at a super price!

    Reviewed in the United States on December 7, 2023
    Number of Items: 1Verified Purchase
    I was late discovering this brand but I gotta say it's a "cut above" ha ha! This system allows you to extend the blade longer if you like, which is sometimes helpful, depending on what you are cutting, compared to the knives that have short blades. The blades seem to last longer than generics too. They make a mini version that is nice but doesn't have the tightening wheel which is why I like this style better. Thanks.
