Unless you NEED a "dive knife", I'd go with the Buck Nighthawk. To me at least, it is a much "better" knife, is a little more "useful", and costs ALOT less than the Intrepid series.
Also, the only sharp edges on the Nighthawk are on the blade, and the handle (with the "rubber" inserts) also feels MUCH better to me than that of the Intrepid.
