Where's the scratches?
I've been a bicycle mechanic for years. Before professionally, my friends used to bring me their bikes to work on. I had an original CRKT M16 aluminum in my pocket, way before the auto lawks. Buddy brought me his bike late at night, super dark out. He goes, it's making a clicking noise (single speed bike). I go out to ride it, get down the driveway, onto the road maybe 40 yards and the road has a slight incline. I put some torque on the pedals hoping to hear the click and boom, chain snaps. I went down on the knife, scraped off a good bit of aluminum and had a bruise in the shape of the knife some time later. I still have that knife.
I know it sucks now but I find and I "damage" a knife I end up using it harder and making more memories with it than one I try to keep nice.
