Posting pictures is fussy and iffy around here. The reasons are simple. I am inept. I work from a disorganized computer. Still, it's sometimes easier and more fun than trying to create a few dozen words of coherent thought, hence the knife photo.
I've had others, but Davie Jones snatched them because I neglected a first principle of seamanship: Any knife you use at sea (or, in one case, on the Kawishiwishi River in the far north woods) should be tied to your body.
It is a marlinspike knife, or a bos'n's knife, or a rigger's knife, among other names. The sheepfoot blade reduces surprise punctures in your sails. The spike is for marling, from "marlin," a nicely aromatic tarred twine. To marl is to wrap marlin around another line, for appearance, chafe protection, better gripping.
The spike helps Jack separate strands of the marlin and to wind and tighten it around the larger line. It sees just as much use in splicing and complicated knotting. It punches holes in leather, canvas, and annoying ship mates.
In one case, a Buck version also intimidated a young lady security attendant at Washington National. This was pre-TSA, in the era when carrying a pocket knife into the Friendly Skies was not ,
ipso facto, a terrorist act. She summoned a mature cop who shrugged it off and waved me to the boarding area.
Geeking it out: A marlinspike may also stand alone, a simple tapered metal thing. A wood version is a fid. You are now prepared to go to sea.
This one is marked "Spencer 1976." The white paint number suggests it may have been issued to a cadet some where. Damned midshipmen kids are always losing stuff.
