OLFA18mm Heavy-Duty Utility Knife (L-2) - Multi-Purpose Custom Cutting Depth Precision Knife w/Rubber Inset for Increased Precision & Snap-Off Blade, Replacement Blades: Any OLFA 18mm Blade

The very best quality and durability. Easy to use and hold.

I have a 25mm I bought at the big box store.I had been looking for the 18mm since I have a supply of blades from all the others that have broken.For some reason the box stores don’t carry the 18mm.These are great utility knives, as they are ergonomic and the thumb wheel lock is superior to all the clicker brands.Hands down the best one I have found so far

This Olfa craft knife is superb. Cuts foam board like butter. Always return the blade to its sheath after use because the edge it too sharp to be left exposed.

I was first introduced to these while employed in a digital printing and print mounting lab. These far surpassed using standard utility knives. Rather than having to take a knife apart to change a blade these allowed us to just snap them off and be ready to go within seconds. They also enable the user to extend the blade further out for cutting things like foam that has some thickness to it. I highly recommend them.

The knives are good quality, equal to NT Cutter or HYDE.The main issue, is if you are in the habit to stow the blade each time you finish, but have multiple boxes, it requires excessive thumbing to tighten/loosen the thumbscrew. or two hands if you want to be certain the blade is tensioned with the thumbscrew.There are no incremental detents when deploying the blade, its smooth.If you typically deploy the blade and leave it out until you are done for the day, there are no downsides to this knife.

Great quality, very solid. I can tell it's made in Japan.Heavy plastic and rubberized handle. Very solid. Comfortable to hold.I only wish it was possible to have a tab to retract the blade in and out easily. The screw wheel takes a while to screw and unscrew. But I am still very happy with the product.

I have used it a couple of weeks and have not changed blade, yet! I use it as a box cutter!

I have nothing but good things to say about this knife because of its quality and because it really is much better than the one I had before. I really like the ratchet wheel for securing the blade at the length you want it. It doesn't have the usual click steps like many snap knives do but I am okay with that because it allows me to set the length wherever I want it.Once tightened down with the ratchet screw the blade is very secure and will not pull forward when cutting like the other cheepo one I have. The knife feels comfortable in my and hand and I feel safe using it for what what it was designed for.I am sure this will not be the last OLFA product I buy from now on.
