### ⭐⭐⭐⭐⭐ Superb utility knife-
*by  on Reviewed in the United States October 23, 2025*

Over the years I’ve tried maybe 20 different utility knives of various brands and sizes (9mm, 18mm and 25mm). The one I always end up coming back to, is this 18mm WorkPRO knife; it’s build quality is superb and it feels solid in your hand without being too heavy, it’s easy to deploy the blade and it stays in place with a solid click, and it’s equally easy to retract the blade back into the handle. The blade is made of SK5 steel, with a black, very smooth coating. It slices amazingly well. Replacing the blade when all used, is also very easy, following the steps depicted in the inclosed instructions.I have rarely given a utility knife this much attention, as I have with this one, but it simply deserves it. I believe my search for the ultimate utility knife has been completed,Giving it a 5-star rating is a no-brainer!

### ⭐⭐⭐⭐⭐ Great knife
*by  on Reviewed in the United States May 19, 2026*

Best knife in its category. Well built, sharp.

### ⭐⭐⭐⭐⭐ My favorite utility knife.
*by  on Reviewed in the United States December 10, 2025*

This is my favorite utility knife. I had the OLFA knife with the twist lock, but locking and unlocking the blade was a pain. This one is really simple and the blade is secure. It retracts nicely and the size is comfortable in your hand. The blades are scary sharp but they can rust so keep them dry. It's a great value.
