OLFA9mm Stainless Steel Graphics Knife (SAC-1) - Multi-Purpose Retractable Art Utility Precision Knife w/Snap-Off Blade, Replacement Blades: Any OLFA 9mm Blade

I use this for woodworking and paper crafts. Works as a utility knife but is also shaped to do tasks I would do with an xacto knife. The break off blades are super convenient, as I can do mean things to it and just break off the dull section of the blade when transitioning back to something that requires precision. I like the angle of the blade which allows for engaging just the tip of the blade. It’s super sharp, fits well in the hand, and a great value for its sharpness and durability.

DAS Bookbinding's Darren recommends OLFA (though he prefers a different model) and now I'm fully converted. It's simply a perfect knife. I was worried it would be too small for my large hands but I find no issue there. Super duper sharp, cleanest cuts I've gotten from such a small blade. The snap off works better than any one I've tried. Everything is satisfyingly tactile and the whole unit is machined to perfection. Stop using cheapo knives and get OLFA.

Easily the best Razor knife i have ever used. I recommend this one. GREAT for detail work, and made to last. AAA Quality.

I needed a knife to get into some tight spaces cleaning up 3D prints. This is the highest quality, best feeling hobby/craft knife I have ever used. The blade is extremely sharp and holds an edge for a long time. Cuts paper, cardboard, PETG and PLA with ease. They cost a little more, but last far longer than any of the cheaper brands.

I've had earlier versions of this Olfa knife for many years, and think this one may have some slight improvements over what I remember. I like the way this knife does not require two small sliders to adjust it, although the pother design does truly lock at a given position. It also seems a bit more comfortable, like it may have been slightly rounded a bit more.I ran a model and prototyping shop for over 40 years, and we went through a lot of these Olfa blades! (Along with the more common round handled hobby knives and their blades, which I bought by the 1000.) What I really love about these is how handy having a sharp blade is—unless you're at the bottom of the blade, there's always a fresh one just a snap away. They're also quite handy for when you have something light but thick—like foam—to cut, as you can expose a longer blade when needed.This handle is more expensive than the knock-offs out there, but I feel you get a nicer tool for the money.

The 30-degree angle on the blade point makes it easier to control with precision. It's a fantastic product in all respects. If you like quality tools, get this knife!

Quality tool. It’s razor blade sharp and has a good weight and size. Very happy with my purchase.

Had a similar desalt knife I've always loved. Bought a pack of Olfa blades assuming they'd fit. They didn't fit, and u had opened the pack so I couldn't return it. I just bought the new knife instead and it's so much nicer than any other utility knife I've used.
