Hi, I have looked for a answer to this question for a while ,so I thought I would give it a try here, the 110 is a inter frame knife very similar to the Gerber FS, I suppose lot of you have already read that Al Mar wanted Gerber to make a inter frame, so he asked Ron Lake if he would allow it, but Ron wanted royalties, so I THINK Gerber took it to Germany until they could find a answer on how to get around Ron Lake, somehow. They must found a way around, all FS Gerbers have a patent number on them , they changed something , it maybe the half stop on the Gerber, it's not much good on the giant FS3, now to get to the question. Is the Buck 110 a Ron Lake design, was it made before Ron made his first inter frame, and if it is a Ron Lake design do they pay royalties to Ron, I don't think so ,that would be a lot of money, maybe Buck changed something ,but it is very similar to a Gerber FS and a Ron Lake knife. Thanks George God bless
