Exotic wood guitar picks

Playing around with a few exotic woods while cutting and engraving guitar picks. All woods do not burn the same (as I’m sure you all know). I had to go high speed and 60-ish power to keep some of the wood types from burning through. More cool than useful, but I’m excited to try pre-stamped aluminum picks as those could be used to play. Any one know if you can engrave tortoiseshell?[20180303_195803]
