If you absolutely do not want to bounce/whiff, get a military hammer/broad one handed battle axe/steel pick. But they have their own downsides (short, no thrust or very weak one).
My steel pick whiffs occasionally, and it's a 36 pierce heirloom...
Also, I (and the people I play with) believe that the game considers weapon length to be straight, regardless of the actual curves a weapon has. Balbaroth was good at using this "ghost" blade to cut people at distances that the ingame scimitar model wouldn't display as a hit. I think this is another reason the steel pick whiffs.
