Also, I was reading something... I think it was on Bladeforums WAAAY back when and the maker said he always soldered bolsters onto his fillet knives because when he didn't, the flex in the blade would pry up the scales if they were just epoxied on. I've never made a fillet knife and I imagine it depends on the type of fillet knife (really thin and flexible, vs something thicker), but it sounded like good advice to me.
