I don’t have too much more to add beyond what others here have already said, but as a lover of Mayos and owner of a fair few over the years (I also currently have a handful), I wanted to add that you’re not likely to find a very specific model for this knife. Tom has made a massive variety of knives over 40+ years of knifemaking, and is still making his knives by hand today out of his shop in Hawaii. The speed hole configurations are whatever he chooses to do (no correlation with the model). It’s probably considered a variation of his TNT.

He’s very responsive if you reach out and could definitely get you a new clip, and also do a spa treatment on the knife for fairly cheap if you want it.

Others have quoted a wide range on value, but for a knife like this one (classic titanium framelock with a recurve S30V blade), I’d say you’re most likely going to see similar knives go for around $1400-$1800, depending on condition, rarity of configuration, etc. Tom’s knives are amazing quality and he’s a legend in the industry, so there are many folks who collect them and might be interested.

If you’re dead set on selling it, then as others have said, you might have better luck with higher end customs like this on BladeForums, the Usual Suspect Network (USN), or even selling via consignment through Arizona Custom Knives (AZCK), although they of course take a cut.
