Rex,
They will "not" install a compass. If the knife is ordered with a butt cap you can get a wrist thong but Randall is reluctant to drill the G-10 to install one. All of the above is because G-10 is hard on the 3 "B's"...Blades, Belts-n-Bits. Metal spacers are doable and you had best have the exact sized piece of material as they do not want to have to whittle it down for ya'...
Hope this helps, Capt. Chris
