This is sort of a primordial origin of the Knifeketeer. It doesn’t really involve the character at all, but you can see the germ of the idea forming.
It’s not really that unusual of an idea, a superhero who murders villains with knives. Wolverine is a superhero. He murders villains with knives that are built into his arms. He can also heal really fast, and has an unbreakable skeleton, but without the knives, he wouldn’t be much use. He’d mostly serve as a distraction, allowing the enemy to beat him mercilessly while the rest of the team does more important work.
I think he’d be called “The Pummelee.”
