: Do you (or does anybody else) have a recommendation for a good knife to carry
: while sea kayaking? I assume you have yours attached to your PFD? Do you
: prefer a blunt tip or pointed?

Gerber River shorty is compact, regular Gerbers work fine also, small dive knives, one of the sharpest blades especially for rope and line are the Spyderco knives (they come fixed or folding and the folding ones open quickly one-handed with your thumb). Knives don't float, sometimes I add some foam wrapped in bright electrical tape.
When you fasten it to your PFD, make sure you don't have some part of the sheath or knife sticking up or out where it can catch on a line or bungee when doing any type of reentry.
I've seen people snag knives, whistles, etc. and not be able to reenter kayaks and rafts when they needed to. Have also seen whistles fastened to PFD zippers, catch and unzip the PFD and compromise floatation and safety.
I usually grind the tip down a bit if it is very pointed, just to protect my fingers, dry suit, etc. from accidental pokes and tears.
Some people have used parachute hook type blades (seat belt type slicers) for safety but I have trouble spreading my peanut butter with them.
