With the past year I believe it was a well known knife maker that released an item I am trying to locate but can't. It was perhaps a 4-5 inch long cylinder, probably made of titanium, that unscrewed at one end and a spike would be removed, flipped 180 degrees and then the base of the spike is screwed back into the cylinder, which now becomes the handle. It was a nicely machined piece that I want to explore further but I can't recall its name or who made it. I've asked AI for help with no luck. I am hoping there is a person who is smarter than AI who can help! ;-) and point me in the right direction. Thanks in advance for any assistance you might be able to offer.
