I finally settled on the knife for me.
SOG TWITCH II
I've been looking for a compact and slender pocket knife (one handed opening) that will primarily serve in an emergency (worst fear is probably No. 1 with everyone - falling overboard caught in a line).
Compact and slender with 2.68" blade. Absolutely one-handed (spring loaded) opening. As lightning fast as a switch-blade. Hard anodized-aluminum handle and AUS-8 stainless steel cryogenically heat-treated blade for a razor sharp edge. If it ever needs sharpening, it'll take to a stone very nicely.
