## Questions & Answers

**Q: can extra blades be stored inside the handle?**
A: No, there is no compartment in the handle to store extra blades.

**Q: This product says auto-lock mechanism.. does it have a spring that automatically retracts the blade?**
A: No, it locks in place and does not spring back automatically.  Our KuttO #30 and MSRZ3 knives are self retracting or the OLFA SK7 is a self retracting knife that we are not currently selling

**Q: Can I purchase a pack of knives? Not just one single?**
A: seen.  Buy as many singles as you'd like, but each one packaged separately.

**Q: Will this work for cutting intricate stencils out of felt material?**
A: Hello Rebecca,It might work, but for detailed work I'd go with the OLFA SAC-1 GRAPHICS KNIFE.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Everday Use
*by M***  on August 19, 2019*

I tried this as a pocket knife replacement, at work there's copious amounts of tape and cardboard and cling wrap to cut, and outside work packages mostly, the odd string, paper and such, mail and the like; I've always had a pocket knife but grew tired of cleaning tape residue, and sharpening blades that I could never get razor sharp, and even when I got close they would dull and chip if dropped. With a slight mod to the clip (sanding down the inner nub, for easier sliding into the pocket), I can now do all the pocket knife tasks aside from stabbing one in self defense, yet slashing is still available, without having to constantly maintain and worry about dmaging or losing my knife. Not only are these so cheap you can buy 10 for the price of a decent knife, you can also easily snap off each blade that is dull, or chipped or covered in residue, providing a new sharp edge. I also own the ss version but like another review stated I enjoy this one better, feels better in the hand and also doesn't have any sharp metal edges that would scrape my hand when entring into my pocket. The construction on these are sound, nothing feels cheap or readily breakable, for the price of a pen you can have a cutting implement that will surpass your expectations.

### ⭐⭐⭐⭐⭐ Solid product.
*by M***Y on June 2, 2025*

I've switched to only using OLFA brand knives for hobby work. Adjusting the blade length is never a problem like I have experienced with other brands.

### ⭐⭐⭐⭐⭐ Well built little utility knife
*by S***S on March 7, 2025*

Great little knife for opening packages. Built better than a lot of the cheaper ones here.
