I've seen all sorts of beautiful Hinderer knives and a lot of the available add-on accessories for them. Most cost more than I'm willing to spend or aren't really my style. I wanted to "personalize" the XM18 that I bought from Vesp last year to make it a bit different. The first attempt was just a filler that fits between the regular spacers. It was made from brass along with a brass filler tab for the pocket clip filler tab. Both have tritium slots. I've never seen someone utilize this spot for an add-on accessorie but it seemed like a simple modification without doing anything permanent or difficult. When I remembered that I had some bronze (I liked the way it seemed to blend well with the titanium and brown scale), I decided to try something a little different. The 3 holes for the spacers were transfered to the bronze for the holes to be drilled. The original spacers will not be used for this, just the studs and screws. Next a scrap piece of aluminum was drilled with the same hole pattern to allow the new spacer to be mounted for milling operations. After roughing out the basic shape, I decided to keep the profile of the exposed section squared off, not to match the contour of the frame. I also added a green tritium in the slot. Anyway, after several hours, the new spacer/liner is in place. I'm undecided as to if the sides should be chamfered or not. I also made a bronze filler tab with tritium for the pocket clip tab and a bronze disc to replace the stock one. Everything can be switched back to stock within minutes. I know not everyone will like this but so far I'm enjoying it. The sloped ramp up front feels really nice when my thumb is placed on it while open. For some reason the bronze spacers profile reminds me of the horses mane... Feel free to post any modifications you've made to your Hinderer!
