Bianchi used a couple different marks, when he used one at all, they are:

“BIANCHI” on one spur and “VICTORIA TEX” on the other
“HAND FORGED”

It is thought that those marked BIANCHI are older than those marked HAND FORGED. No matter what his Victoria or Bottle-opener shank proved enormously popular and was emulated by many other makers including Buermann and Crockett.
