belt clip is softer that I would like.

Solid, belt clip is softer that I would like.
It feels good in the hand
Review by Rikki X.
Verified Buyer
If you're concerned that the handle will be too thick for concealed carry, don't be. It is around four times wider than the blade's thickness. It feels good in the hand.

I secured the sheath to the inside of my key wallet by drilling holes in the leather in the middle compartment and then securing the mounting screws through those holes. I discarded the belt clip.

Perfect product, read the description
Review by Arron Q.

Perfect product, read the description. This is a small knife meant to be used as a last resort for law enforcement or military personnel. The blade is nice and strong as well as very sharp. The grips are plastic and feel a little cheesy but it’s a 35$ knife intended to give you a fighting edge, not to look pretty for Instagram. The sheath is great, sturdy and can mount on duty belts or molle webbing, perfect for LE and military personnel.

Was Sent a Used Knife
Review by Shealyn W.
Verified Buyer
First, I am disappointed with Amazon for having sent me a used knife. The plastic sheath was all scratched up, box was crushed and had been closed with scotch tape. To top it off, it was sent to me in an envelope instead of a box.

The knife itself was made in Taiwan and it shows. Not anywhere remotely near Ka-Bar quality. Knife wiggles while inside the sheath. The handle is thinner and shorter than I expected. Getting a grip on this knife is not as easy as all the marketing videos show.

In real life it would be just as easy to fumble with it as it would with pocket folding knife. Also, mounfing it on a duty belt is impossible with the short screws that came with the sheath. Average duty belt is around 3/16 thick. The screws barely reach the middle of the female nut.

Overall I feel I was taken advantage of with this knife. Maybe Amazon sent me a cheap knockoff instead of the real thing. Either way, this knife is going back to Amazon.

p.s. The only reason I gave it two stars instead of one was because maybe someone out there might actually have bellow average tiny hands, an extra thin duty belt and likes buying poorly packaged scratched up merchandise.

Good tool if your pistol is compromised
Review by Stephani C.
Verified Buyer
Hope I don't have to use it. Nice fit & Finish. Only problem is wobble on the belt . The belt clip is wider than the most common belt width. Fits close to the body. Undetectable under a T - shirt or open sport coat. There is another model that has a slightly longer blade if you wish to have a big knife.
Great Knife Overall
