The wood handles are nice, but if you want a better grip, go for the "Sure-Grip" rubber handle.
Also, I strongly recommend getting the ATS-34 steel, rubber-grip version that Buck sells exclusively through Bass Pro Shop. Buck's ATS-34 runs circles around the standard 420HC. I dressed my last deer with the ATS-34 version and was very pleased with the performance. The knife takes and holds a fantastic edge; it has a good blade size and geometry as well.
I agree that the sheath leaves a lot to be desired. I'm thinking of getting a custom kydex for mine.
