A lanyard hole is a bad idea on the model you asked about in my opinion and this goes for the 110, 112, 500, 501 and many of the others built this way. I saw one 110 done successfully but it was a very old one with a different pin pattern than the new ones and even that was risky I think. I have never done that to a Buck like these and won't. Too risky.
With threading the key is to not perf the other side and to be sure you are not drilling into or threading into a pin that may be highly polished and invisible to you at first glance. The holes need not be all the way through to give good threads to grab to they need only be good to get about 7 good twists of the threader.. Thumb studs are fine. Easy enough with the correct size carbide for the screw size you are using but even that can heat the blade if you don't do it right. I've seen some burn marked which means they softened the metal (annealed) a bit there in that one spot anyway. It probably didn't hurt the edge at all but the mark is a needless thing to do. If you keep the blade cool you can zip through there pretty effortless if done with the right tools. .
I'm easy to reach if you need something or just some advice on how to do it yourself. Next time come to my place and I'll be more comfortable talking about that kind of thing. Here its probably not something Buck wants to see a lot of. Thanks for your patience Joe. I think you know I won't make a habit of it. :thumbup:
