I'm seeking advice from those who may have made the same mistake. As I'm a novice maker, I've been using wood from my property as handles because it's free. I had some that had a really nice look to it and of course this stressed spot gave way to a crack/void as I shaped it that was hidden underneath. I think I read here before that sometimes glue is used to fill these voids and seal (as best as can be) the wood from the defect becoming worse over time. A quick search of CA glue and I see on Starbond's site alone 23 types of glue. I'm assuming a thicker, gel type to fill the gap then thin for the entire handle for uniformity. This is just a guess though so any and all advice is greatly appreciated.
