Not me but my dad over the last few years. It started with the stainless Ruger Super Blackhawk which I have had since early 90s. Grips are by LS Grips which are best simulated Ivory I have found. I have carried the SBH in Alaska for work and wanted a tough polymer and these grips have such a good off-white color and a slight grain too. I had the Buck 277 (ATS-34) and then pulled a pair of polymer scales off a 279 I found (also nice off-white polymer), sanded off the machine applied scrimshaw and sent to my dad…gave him the 279 and rosewood scales off 277. On both the SBH and the 277 I sprayed the grips/scales with a light coating of textured clear acrylic, protects scrimshaw and gives a slight grippiness to the handles. Then I bought the Buck 193 (also ATS-34) on a whim, sanded the machine scrimshawed bear off the polymer insert and then sent to my dad. Lastly I had him make the leather pocket slip for my Victorinox multi-tool to complete the set. He is retired and loves doing this stuff.
