Sometime last year, Irwin sent over a sampling of their new folding utility knives. This one, model FK100, is the simplest of the bunch. There are no fold-out tools, and there is no built-in spare blade holder. It’s a folding utility knife with no frills or excess.
The FK100 folding utility knife, when closed, measures about 4-1/16″, and that’s from point to point. It’s a compact and very pocket-friendly knife.
Blade depth is not adjustable, but there is a cutting slot that’s useful for trimming wires, small cord, and other types of materials. There is also a tool-free blade change button.
The knife ships with a standard bi-metal blade. It’s not a super premium blade, but it’s not a junky blade either.
Ergonomics are decent, and better than expected. This isn’t my favorite folding utility knife, but it’s one I don’t mind using. The knife opens easily, and there are spacious and gently-grooved thumb and finger rests on the top and bottom edges. It’s a comfortable knife to use.
Lockup is strong and secure. The knife only opens and locks to one position – fully open.
Blade changes are quick and easy. The tool-free blade change button only works when the knife is opened to a 45° angle. When – not if – you forget how to change the blade, markings next to the bottom help jog your memory.
On the back is a removable belt clip. Again, as with the rest of the knife, the belt clip isn’t flashy, but perfectly functional.
Overall, I find this to be a good knife. There’s nothing fancy about it, but there also aren’t any cut corners. It’s a solid basic folding knife.
