CIVIVIVarius Fixed Blade Knife with a Kydex Sheath, a Finger Ring and Conventional Handle, Full Tang Knife with 3.26" D2 Blade G10 Handle for Men Women C22009D-1

Craftsmanship TOP NOTCH, LOVE CIVIVI, wow you could not make a worse handle replacement design, this is almost dangerous, MAKE SURE YOU KEEP SHEATH ON, and once your torx slips, thats it, you are out of luck - DO NOT TRY TO TORQUE IT TO DEATH - you will just strip the screws, BE CAREFUL

The knife is amazing and works amazingly! There's one thing that could be improved and that's the clip. It could be just a bit tighter so that you can pull the knife out quickly and the holder won't come with it in a self defense situation. Other than that I have no problems other than that. I see other people say that the handle replacement is a bad design and I haven't used it because I love the handle it comes with installed. But besides the clip, it's an amazing quality knife for an EDC that can be hidden!

I bought this blade for the purpose of the interchangeable ringed handle. That purpose is gone because the screws are tiny H-6 hex screws and arent budging at all. Now they’re stripped and now I am unable to use the handle I bought this knife for. Expected better from CIVIVI

When I got the knife, I was excited to get the different handles on it realizing that the handle scales it comes with don't lend well to me because I have large hands, but when I went to take the handle scales off, I could not get the screws out. They seem to have been torgued down so tight that the threads sheer when you try to remove them. Currently, the knife handles are not usable for me, and I am very disappointed. The knife itself is fine, the low rating is for the key flaw of not being able to actually remove the handle scales as advertised.

This is a very durable knife and the blade came sharp enough to easily slice paper. The case seems very durable and hold right to my pocket.

Wanted to swap grips, only to find that the screws were so tight it would never happen. Even put it in a vice and cranked as hard as I could. Now the screws take circular bits.

Very nice knife. I have hade the problem everyone else has been having. Screws are impossible to remove. Hopefully I never want to switch handles. Knife will have to be protected and put in a vise to remove the handle screws. Not looking forward to having to do it that way.

The knife is sharp, lightweight, and ergonomical. I stripped three T-6 torx wrenches trying to change out the handles. Lousy handle design for handle change out design. I finally just drilled a lanyard hole in the handle that was permanently affixed.
