OLFA 25mm Extra Heavy-Duty Utility Knife (NH-1) - Multi-Purpose Custom Cutting Depth Precision Knife w/Ergonomic Grip Handle & Snap-Off Blade, Replacement Blades: Any OLFA 25mm Blade

This box cutter cuts safely and nicely even the thickest of boxes. Just be very careful as it is very sharp!

I use this for terrain crafting - mostly to cut or sculpt Foamular rigid pink insulation foam. The blades are sturdy and build quality excellent. I’ve never had the blade move or slip even when well extended to cut thicker pieces.

Solid knife. Great for people big hands

I use the daily as a belt guy only down fall is I break the platic that holds the blades

I use this knife, which uses 1" wide break off blades, as part of my work as a contractor. I have tried at least 6 or 8 different snap off blade knifes in the past and this one is by far the best of them all. The blade is really sturdy and does not break off easily. The metal sheath that holds the blade keeps it straight and does not allow the blade to wobble around. The black knob that tightens down to hold the blade in position is easy to adjust with just my thumb and I can quickly loosen the blade, slide it in or out and re-tighten that blade with just one hand. The blade is also really easy to change and the yellow body is a nice size and fits well in my hand. The only thing this knife does not do is store extra blades in the body. But, I do not mind that since the replacement blades come in a really nice plastic case that is easy to carry in my tool belt. I have had two of these knives over the past 5 years and will get another one when my current one wears out (or I loose it...again).

I love this knife! It cuts through thicker materials with ease, is easy to change the blades, and is incredibly durable.

I was so excited to get this amazing, strong, Japanese blade knife! I even upgraded from the 18 to the 22. The strength and sharpness of a Katana with the ability to quickly snap off old & reveal new. It replaced my pretty Snap-On utility knives & many Bloody Mary’s. Imagine my surprise when the wheel cracked on my first day using it! I am a girl over 55 years old so I am positive it is not my Samurai strength. I lovingly put black gorilla duct tape around the broken wheel to try to hold it together. I am not sure how long it will last. I cannot return it because I am in the middle of a project and have tasted the joy of a perfect slice. Unfortunately, with my knife I also purchased the EXPENSIVE bundle of replacement blades. My simple pleasure has been engulfed in cognitive dissonance. I yield to dichotomy as I wield the strong blade encased in a delicate tsuka (handle). My joy, reflective of springtime in Osaka as blurry of cherry blossoms danced in a gentle breeze, is now paired with a night on the bathroom floor after too much sake. My projects, love, and pain- exist in wabi-sabi.

This is a slight upgrade from the typical yellow utility knives from Home Depot. The handle/grip has a tacky type of plastic that has better grip and the blades are snap offs, but really quite sharp. The muted grey colour is a nice touch. It’s a quality piece that fits well in hand and cuts perfectly. Recommended.

This is not simply a hobby knife, this is a tool. Feels so solid, professional, has good weight, and a nice grip. And the blades are sturdy, this will cut anything. I do use it for hobbies, cutting thick leather is easy with this tool, along with cardboard, anything you'd need a knife for. Very sharp, and easy to sharpen the blades to make them last longer, holds an edge well.

Functions same as the typical, with slightly better grip. Being anything other than yellow is a huge plus because others don’t confuse it with their own. Also gives you a professional look by having a professional knife that is a step above the rest.

This is my second purchase of this knife in the last 4 years, but the first is still going strong despite getting beaten up constantly. Hands down the best OLFA, but not sold in Home Depot. Solid build and large body makes for a good firm grip. When the silicone handle breaks in a tiny bit it really is a super comfortable knife that allows you to control your blade well. The rubber is way more durable than I first expected when buying it. The slide wheel still opens and closes with a thumb and blades are easy to change as with other OLFAs. Fantastic jobsite knife.

Work as it should. Olfa knifes are the best.
