My reviews of past threads and internet searches puts the often-lamented (at least, by me), defunct Carbon V as being 50-100-B (aka 0170-6) steel made by long gone Sharon Steel and used also by Camillus, etc. Today we can buy one-piece, forged knives such as the CS drop forged hunter in 52100, a similar carbon steel. I have ordered one, with great hopes for it.
