I have a leatherman on my PFD and carry a Sypyderco Harpy in my pocket. The Harpy has worn shiny over the years as I always seem to be grasping/holding/playing/fondling it
Occasionally I may forget it, say if taking off my jacket, but some seconds later I miss it and go retrieve it.
The leatherman is actually used more, virtually everyday on the boat, but the Spyderco is always there for the serious quick line-cutting work.
Btw, I've been MIA for awhile, feels good to get back to SailNet.
