Dillinger: I agree, kukri is awesome design. Check out Cold Steels two handed model - devastating and can be thrown 30 feet w ease. Check out their video.
I purchased spyderco's sharpening system and you can sharpen anything - serrated, straight or scissors etc. YouTube has plenty of videos on it. If you sign up for Cabelas CC, they usually give you a $20 credit which offsets the cost of sharper or knife of choice.
My EDC is Spyderco's para-military - S30V - straight edge.
