Every Ben's knife is engraved with a number corresponding to when it was made in relation to the other knives. The form of the blade makes it possible to recognize in which period of the blacksmith the knife was forged.
There are 288 different Ben's Knives in total. The serial killer or blacksmith Benny Delon forged a unique knife for each victim he killed, showing that he had 288 victims.
Ben's knives are known to be exceptionally sharp, enough to cut Silva Zoldyck's tough skin. At least one of them is imbued with a toxin so powerful that 0.1 mg of it could paralyze a whale. The aura of their forger remains in them after about a century from his death.
