I've never had a knife with the mudder handle. I'm really looking forward to it. It looks like it will be very ergonomic, and good for a variety of grips. That's what I like. It's also why I don't really like the ASH-1 handle... I tend to use an inverted grip sometimes and that particular grip just doesn't work all that well inverted.

Busse's TAC handle works great inverted, the Special Forces handle works pretty well, too.
