Great knife

Purchased this assisted opening knife to replace my old knife which has gone astray. Definitely an upgrade. Feels great in hand. Opens smoothly. A little more difficult to close/unlock then expected. It is very well crafted. This is a knife that will be used as a daily carry. Came sharp enough to shave some hair. All in all a worth while purchase. I would definitely recommend this knife.

My Pocket Buddy M4

I own two CRKT M4 Carson assisted open pocket knives. The Bone and Horn and a Burl wood scaled models. I have collected and used pocket knives for over 60 years. I find the M4 flawless in design and comfortable use. Its difficult for me to choose my " pocket partner " for the day, because they are both comfortable to carry and dependable to use. I hand craft and design custom Pistol and Rifle holsters for sale to area target shooters and big game hunters. They invariably ask my advise on knives I choose for my work and carry. When I show off my M4 Carson a flurry of questions and comments arise, often resulting in a custom belt knife holster sale for me to carry their new M4 in.

best assisted opening

I love this knife. the thumbs for opening are great. this is the best assisted opening knife I have every owned. i was scared paying 50 bucks for a folding knife, but man it was worth every penny. it also comes razor sharp and the bone handel is great.
