I have used quite a bit of unstabilized koa, and I use it on kitchen knives that see a lot of use and get soaking wet as a matter of course. Having said that, I apply Tru-Oil generously. The handles are very well sealed when I'm done with them. I have seen no difference between stabilized and unstabilized koa as far as moving or durability.Beautiful knife, Ty. That koa looks really good. Question, does koa need to be stabilized?
