Link? We don't need no stinkin' link; we could do our own hobby knife survey! For example, I keep no fewer than four knives with Number 11 blades in them:
1. A general-cutting knife for removing parts from the sprues.
2. One with a brand-new Number 11 blade; the blade eventually goes on knife Number 1. I painted the end of the handle blue for identification purposes.
3. One with a blade that I dulled by scraping on the concrete outside my apartment and use as a putty applicator; the end of the handle is red.
4. One that I use for cutting paper and cardboard as I got tired of tearing up my other knife blades every time I wrap Christmas and birthday gifts. The handle end is painted white.
I keep one more separate knife with a Number 10 blade; its handle end is painted yellow.
I keep two more larger knives, one with a Number 2 blade and one with the larger counterpart to the Number 10 blade (or is that the 2?). I rarely use them, actually.
I've got various-shaped other blades that I had acquired years ago, like a chiseling blade but never use them. I could get rid of them, I suppose, but then two days later, I'll want one of those alternative blades!
