do not buy this Stanley box cutter, i purchased one and the blade does not really lock into place, it came out and i almost cut myself. i contacted Stanley who said it's produced in China and don't have control of the release mech used, so they sent me a replacement box cutter, can you believe these ah's that sent me one that sells for 1 dollar, they can go screw themselves. I no longer purchase any Stanley products. I wasn't concerned with getting one worth more money, but they at least could have sent me one that was "NOT" worth less than a dollar. I paid $10.00 for this one.
