## Questions & Answers

**Q: What's the secret to removing the old blade and inserting a new one?  Does it slide in and out from the back end?**
A: I've never had to remove the old blade and replace it. I just use pliers to snap off the dulled little piece which reveals a new, sharp edge. Once the whole blade is used up, I usually just toss it. I don't know if it's replaceable or not.

**Q: Where can I get replacement blades??**
A: hardware store,  walmart.

**Q: What do you do when it jams after you replaced the blade? This didn’t happen the first time I replaced the blade**
A: Just take it apart and clean it with soap and water and a small brush (like a toothbrush). This is a precision made tool, and by and far the best in it's class I might add. The specs are tight, so if a little debris (such as dirt or pocket lint), gets into the sliding track grooves, it can block the blade from extending. Remember to air dry the parts separately before re-assembling. With proper cleaning and care, this high quality, heavy duty tool will dutifully serve you for a lifetime. I keep this very model on me at all times (L-500GRP).

**Q: Does it have a belt clip?**
A: No.

### ⭐⭐⭐⭐⭐ nice cutter
*by S***. on January 2, 2026*

Very nice cutter. Nicely made and feels great in my hand. High quality blades stay sharp a long time.

### ⭐⭐⭐⭐⭐ The envy of all box cutters
*by J***N on December 26, 2025*

Love these guys. Great quality and super sharp. I abuse the heck out of them and they just keeping working as smooth as the first day I purchased them.

### ⭐⭐⭐⭐⭐ Super sharp and easy to handle; helped me move apartments
*by M***G on June 27, 2021*

With my old go-with-the-cheapest box cutter on its last legs/blades, I decided to shop around for something a bit nicer to replace it just in time for moving into a new apartment. The NT Cutter wasn't much more expensive, but it sure as heck was a lot nicer. Since getting it a few months ago, it's been through some brutal box and packing tape cutting, including really hard multi-ply corrugated cardboard boxes that held appliances and heavy furniture -- and even the dense sort of boards that protect furniture corners (for which I probably shouldn't use a box cutter). For the vast majority of boxes, it slices through like butter, never catching or tearing except on the gnarliest packaging. The edge has certainly started to visibly wear by now, but its performance for my purposes is largely unchanged (especially now that I've gotten through the move in large part). The size is perfect for my small hands, and I really like the clicky extension/retraction -- much smoother than my old box cutter. Really happy with this knife, and would be glad to keep refilling it with blades.
