Good knife for the money, but mine had too much friction, was difficult to open reliably. The thumb stud is small and sharp. After oiling, buying tool to adjust pivot and opening 300 times, finally works as it should. Now I love it.
I have carried these Kerdhaw knives for years. Due to my stupidity, I have donated a few to TSA and the local sports stadiums. So I am replenishing my loses. Love these specific knives
