uhm... yeah. I'm with RH on this one. As soon as I read the story, I began to wonder about BlackRazor. Who stabs sofas for fun? Don't you people know that sofas have wooden and metal frames? Training with a knife is one thing. Playing with a knife is another.
Reminds me of my cousin sharpening up a butter knife with the electric sharpener and then trying to carve a pipe out of a piece of wood he'd found. Cutting TOWARD his hand, he of course slipped and oops! There goes a tendon. After getting stitches and scheduling surgery, he came home and tried again. Ooops! Four more stitches in the other hand. I wound up carving the pipe and presenting it to him. Since he had no insurance, the pipe only cost him about $3500.
Some people shouldn't play with knives.
That said, I plan to give him a CRKT Mirage for Xmas. That was ten years ago, and he seems a little older and a little wiser. Let's hope BlackRazor gets a little wiser too.
