I think I got my first pocketknife when I was around 7 or 8. Before that, my father let me use scalpels he brought home from work to learn to carve balsa. I think he knew that would make me learn to respect blades. A few sliced fingers later I knew how to handle sharp things with respect. He always advocated letting us learn through doing and from our own mistakes. Unlike today’s helicopter parents. I guess that was my rabbit hole.
I have carried one blade or another in the five decades since. All sorts, from Swiss Armies to multitools. For awhile I was into woodworking and got deep satisfaction from making chisels and tools “scary sharp.” A few blades over the years have been sacrificed to the TSA gods, when I forgot they were on a keychain or in a bag.
Now I have gotten more into collecting new and interesting blades, but I still carry several on me every day, from delicate ceramic blades for small precision cuts, to big pocketknives for general utility or a carving task like Jonas described, when the offered knife made me cringe. I have a ChefsChoice Trizor XV to sharpen them to a 15 degree edge if they are strong enough to take it. I get that same visceral satisfaction using it that I did in honing a wood chisel or plane iron to shaving sharpness.
