My steel knowledge is 2" deep and 20 years out of date. I asked my brother about one of those "number steels" last week while trying to figure out which blade to make into a project knife. His response sounded like advertizing fluff; "they're really hard and make excellent knives"

If Charleton's ready made knives are $200ish, then what the heck - GO FOR IT- The blade blanks I bought from him were $95 each...and the ugly knife guys at www.scrapyardknives.com make $200 knives.
The knife I use (abuse) to open cans, scrape dried grass out out of the lawnmower, and other non-cutting tasks is 440 stainless with a 'chute cord handle. I can lose it or break it, and I sharpen it with a file. So maybe my definition of working is bogus.
Here's the "number steel" blank that got my attention to waver from Charleton's stuff . I had to look again to see about the number: CM154
