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.

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.

Extremely High Quality
This is very stout. The ratcheting wheel lock works great. Everything about this say, "quality."

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

Got what I paid for. Mind the handle shape and size.
I work in general construction and have always loved a good work knife. This tool arrived as expected. Those with smaller fingers and Palms, especially ladies, avoid this knife as the handle will seem silly. This is my insulation knife but I have tested it by doing much more. The blade is held by the wheel mechanism with much strength, which for this tool is critically important. The grip is an added touch but this knife is not known for best in class ergonomics. (For that, buy a utility knife where the design shows that it is intended to fit the negative of a hand grip. That is, the shape of the handle is obviously made to be held tightly.). This knife is highly versatile, however, as the user possesses ultimate control of the blade length. That adjustment is the selling point for me, giving varied functionality to anyone’s task-related needs. Believe me when I say that the blade is held stronger than ANY other make/brand - you can have the thing extended way out and still can trust it’s strength, which gives stability and ultimately safety. Some believe that the snap-off blades give the user a sharp blade with more ease but for me it’s easier to change a conventional utility knife. The wheel mechanism is not as smooth as Olfa’s nicer snap-off knives, but for the price this is a winner. For the workshop, the car, the tool box or the junk drawer I’m going to recommend this knife to anyone who can wield it comfortably.

Don't hesitate. Buy this knife. I have been using these OLFA knives for years, based on a recommendation from Dad (decades ago). They are virtually indestructible. The blades last a LONG time and are extremely sharp. You can buy replacement blades almost anywhere. Once you try cutting difficult things with this knife, you will instantly say: "Where have YOU been all of my life!"

Can’t go wrong with Olfa!

Great knife, I’ve owned about a dozen of Olfa knives and will continue to purchase them

J'en avais déjà eu un comme ça. Je l'avais perdu. Bien heureux d'en avoir retrouver un pareil. Très bien pour travailler. Une très bonne prise qui facilite la précision de nos coupe
