I've been carrying a SOG Seal Pup for a couple of years and have found it to be adequate.
However, I am currently re-grinding a Ka-Bar Marine into a much shorter knife, mainly because I've always wanted to do it and also because I think the steel is just about perfect for hard, repetitive use. It's 1095 steel, not some hard-ass nitemare alloy and it sharpens easier/better than any other (cheap) steel I've ever used. No, it's not stainless, thank God.
So far I have clipped the point, dropped it significantly actually, and thereby reduced the blade length to just over 5" and I have ground away the shoulders (this is the area where the bolster meets the blade, where the words "Ka-Bar" and "USMC" used to be). When the general geometry is to my liking I will reshape the edge/sides, shorten the tang and mount the blade in a cocabolo handle, using Gorilla glue of course. The bolster will be brass because I like brass.
And the best part is that nobody will know what the hell it is, except me, and I'll just tell folks who ask that I picked it up at a garage sale.
Oh, yeah, I forget. I don't care how heavy it might end up being. As regards a knife, weight is one pretty silly concern IMHO. It's like worrying about the boil time of a stove.
Practicaly idiotic. HYOH.
