I was pleasantly surprised to find this size of socket for a 1/2" drive ratchet or impact wrench. With other manufacturers, the drive size would have increased to 3/4" drive. The required application at the time would not have accommodated a 3/4" to 1/2" reducer or a larger sized 3/4" drive ratchet or impact wrench. The socket served the special application required.

Was sick of the “Other Guy’s” (Blue) brand utility knives… the blades kept falling out, but not with this! I love that this opens with a flick of the wrist, and even stores spare blades too!

Snaps open with a push of a button & flick of the wrist. Up a ladder 40’, sometimes you just have one hand available. Made of solid steel, carries 5 spare blades. A lifetime tool. Get what you pay for- highly recommend.
Matched my set and looked genuine to me. Thank you!
I'm using it with impact driver to change my tires. To get the maximum torque transfer out of my impact driver, I needed small and light impact socket. And, this one was the most reasonably priced.
easy 1-hand open 8s quick to use and having spare sharp blades a real handy feature do you always have a safw knofe. Prefer ovet the snap off blade because these blades are stronger
Best utility knife I have ever used. Very quick to open and close, pretty compact when closed and quite safe. I used to often be lazy about going to get my old style exacto knife and try to open packages with my hands or a pen or whatever was lying around. Now I leave this knife in my bowl of keys right at my entrance and I use it all the time.
Pretty simple: A very durable product. Performs as I was expecting. No misgivings.
While this is a heavy duty socket, it is too shallow to be sold as a deep socket. Definitely not a true deep socket, at best it is equivalent to any other brand’s regular socket.Well built but incorrectly named.
