Boris - Sharp
Boris wasn't renowned for his intelligence, observational skills or witty rejoinders (although he could drop in a pop-culture reference as well as anyone else, his home being the Kingdom of Loathing and all). However, he was unmistakably sharp in one sense - in his use of an axe. That, or bulging biceps and threats of violence, was all he needed to settle any debate he found himself in.
Trusty wasn't the first axe he ever owned, but it was the last. There was no special inherent property to it - it was merely there during an unusually dire battle, but it won him his survival, so Boris grew attached to it and named it. The actual construction didn't matter to him.
As he refined his axing technique (i.e. started a fight with a random person or creature), Boris chanced upon a very interesting technique. When he tensed up his axe muscles and swung Trusty at just the right speed and angle, it rebounded on impact with a vibration that carried to Boris' forearms, causing the axe muscles to quiver pleasantly. He never again faced an opponent without using the technique at least once, and his physique reflected it. The frequent exposure toughened up those axing muscles almost as much as his ridiculously overboard consumption of raw eggs and meat, contributing to his legendary strength.
