Review: Great Concealed Carry Self Defense Dagger! - The quality of the knife is excellent. Blade comes sharp but I sharpened it more. The handle is a little short if you have large hands but it’s manageable. The sheath is constructed of very stiff glass filled plastic and the belt clip is super stiff but you want it to be so that it mounts to your belt securely. The firm click you get when sheathing the dagger assures you’ve secured the knife. Highly recommend.
Review: Perfect for what it’s designed for. - Perfect little left hand knife to wear next to your concealed carry. The sheath is made well enough and retains the blade well. I have smaller hands and the handle seems to fit well. I could imagine the front of the handle-choil might bite if you really wrench into something, but I haven’t experienced this yet. Blade steel is a reasonable and sharp option so long as you use the knife for what it’s intended for.

## Questions & Answers

**Q: Does the belt clip allow the knife to sit horizontally as well as vertically? Did not understand answer of 7/4/20**
A: No.  It is impossible to move the belt clip because the backings for the screw sets are not an Alan-head.  Therefore when you turn the screw head the backing just spins and there’s no way to keep it still while turning the screw.

**Q: where is it made?**
A: I believe it’s made in Taiwan. Great edc knife and very low profile! Good retention and razor sharp out of box.  Won’t be disappointed

**Q: Can you buy just the holster?**
A: I’m assuming so if you contact Kabar CS but there are infinite custom kydex sheaths on the market for this knife.

**Q: Does this come in serrated as well?**
A: Not the investigator to my knowledge, other TDI Models though, yes.
