## Questions & Answers

**Q: Can you widdle with it**
A: It's not designed for whittling nor is it the world's strongest knife since it's a "folder".  But it IS VERY sharp, opens in a flash, and could be used in an emergency to break a side window or cut a seat belt.For the price, it's GREAT!

**Q: Does the blade lock?**
A: It locks open but no lock to keep it closed but didn't open in ur pocket

**Q: What kind of screw does it have.**
A: I believe they are called Torx bits, not sure what size, but it is not a standard phillips or flat blade. You can get a Torx bit set in the range of sizes that would include the size for the knife's range at any auto supply store, Home Depot, or Hardware store.

**Q: How much is shipping?**
A: mine was free, but i am a Prime member

### ⭐⭐⭐⭐⭐ Great Knife

Great knive, Master USA are quality and priced good. I recommend them!

### ⭐⭐⭐⭐⭐ Great quality
*by L***A on December 30, 2025*

Durable material. Weight is nice. Sharp blade. Works well. Design is nice. Has held up pretty good

### ⭐⭐⭐⭐⭐ Feature Rich & Great Price
*by P***G on December 6, 2023*

The skull artwork design was beautifully done...especially in green. I'm certain the blade material is not a high-end steel, but the knife is an exceptional value providing you with a decent blade, rope cutting capability, glass breaker, spring assist opening, and a belt clip all wrapped up in a cool graphic (if you like skulls). The overall weight of the knife felt lighter than I expected, but was balanced in the open position and felt good in hand. Makes a great gift. Artwork wore off from being in pocket after a year. :(
