Knife making, engine work, and thinking

Got the blue-handled knife looking decent but not great. There is a gap that I'm just not happy with and there's is nothing I can do about it now. I'm going to continue with it and until I take a trip to the bossier city Tandy, I won't be able to make sheaths. I need some hardware that only the hidden tang sheaths take. I also, FINALLY got the simplicity running well and did an oil change on it.
