Anyone ever attempted to just go toe to toe with a wolf, bear, or cat using only a knife or perhaps a spear?

I am a blacksmith and can fashion my own blade for such a hunt. I was wondering if anyone has ever tried and perhaps they can give me their experience.

I intend on doing this soon in the future, and I'll make a post before I go out, lol, that way if you never hear back from me you'll know it's because I lost the fight.
