## 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
