KeyUnity KK00 EDC titanium alloy knife. I bought it and used it a few times for paper cutting, then it sat in a drawer. It's quite small at 6 x 1.3 x 0.6 cm, about the size of a pinky finger. The blade length is 25mm, the steel is 5Cr15Mov, and it cut paper quite well. I don't smoke and I don't have any pets. Thank you.
