## Questions & Answers

**Q: Lost  screw that holds blade, can I get a new one?**
A: Does anyone have a contact for the actual maker of the knife.  Went to TacForce but that is a no go. I have the same issue screw fell out.  Liked the knife up to this point.  They really should not fall out.

**Q: Can you please confirm that the blade is 3" and not even slightly more.  Thanks**
A: I just measured mine and if you measure from the beginning of the edge to the tip it is three inches exactly, however if you measure from the bottom of the blade to the tip it comes in at 3 and about 1/8th.

**Q: What specific steel is this made of, e.g. 3cr13, 8cr13mov**
A: I dont know, its sharp and holds its edge well. I can tell you that i love this knife and have one for each vehicle and I carry one personally.

**Q: Are any parts plastic on this knife?**
A: No.
