Who knows more about this S&W "boot" dagger

Oct 6, 1998
Hi everyone, I have in my 'collection' an Smith & Wesson foldable bootknife that uses a 2-way fold action to get the dagger blade out of the handle and fixate the blade by folding/turning a second grip piece (U shaped) over the also U shaped handle.
I know it sounds complicated, but I can't explain it better. I think the knife is about 15-20 years old (when S&W started to sell knives under their name) and it's in a plastic tray (1/2" high) that slides in a carton cover. The tray holds the dagger opened and a belt/booth sheath with big chromed clip and it's made of fake leather (plastic).The sheath "holds" the folded dagger by way of a big snapper that keeps the folder from ridding up in the sheath The dagger blade is only 3.5" long very pointed and the spine is thick with centrally on both sides a deep bloodgroove. I've never seen them anymore and was wondering i somebody knows it, knows what it is worth or is interested in it. It's NIB.
Cheers, Bagheera

The S&W was made around the late 70's,I had 4 last year in my store that the plant had found in a back room. Sold them for 75.00 a peice and they went fast. They book at between 75.00 and 100.00 in the S&W collectors book. Hope this helps
Thanks for the info, I didn't know their was a S$W collectors guide for knives.
Best regrds, Bagheera
