In a quest to buy them wholesale, I contacted CS Osborne, got their catalog and saw the sail-plams, marline spikes etc., and Jack came to life.
With a box of a dozen of these things, a slab of Mircata, some brass tubing and a few knife rivets, this is the result:
It ain't perfect, in part because this is a utilitarian tool, not an heirloom piece, and in part because I needed to see how fast I could crank one out. It took 5 hours.

I guess that's all for now, oh, I have been talking with people about carrying professional lineman's buckets, stay tuned!!
