OLFA18mm Heavy-Duty Utility Knife (L-5) - Multi-Purpose Custom Cutting Depth Precision Knife w/Reinforced Fiberglass Handle & Snap-Off Blade, Replacement Blades: Any OLFA 18mm Blade

Besides being exemplary at cutting - being able to break and get a new sharp tip makes it so much better than a Stanley knife. I use it for caulking, working it into voids, particularly corners (clean the blade well with isopropyl alcohol beforehand to prevent contamination); and gardening, cutting unwanted new grow off cactus.

Nice Knife. I am a woodworker and use this type of knife for many purposes. Holds up nicely to my varied uses. Oddly enough, I have an Olfa Knife that I bought in decades ago that is still in perfect condition, after all these years.

Bought a couple cheap ones from hf and hd that were terribly unsafe. This one does the trick, so far the mechanism hasn't shown any signs of wear. Great that you just chop away small parts of the blade instead of flip and throw out a whole blade.

This thing is very sharp and has no wobble. It is also very easy to put away as the wheel is not too hard to adjust.

So much better than a standard razor knife/box cutter for many applications. It’s lighter, easier to change blades, and the blade quality is consistently good. The only issue is not having easy and safe disposal of the snap off blades. It would be better to have the handle design include temporary storage of these sharp metal objects.

Excellent quantity. I don't like much the lock sistem but Olfa has different models so I am sure I will find something I will like better. It works so well that I ended up buy a pair of Olfa scissors and a rotary cutter for doing my crafts. I don't want anything else except OLFA 😍.

Good build, strong frame surrounding blade, locking wheel is solid. Sharp blade ready to go.

Best knife for the contractor on the market...I have 3 in my job site toolbox
