Make sure to only get stabilized blanks form people you have been referred to off Fleabay. Lots of what are called stabilized blanks are just coated on one side with varnish. Lots of crooks out there.
I highly reccomend finding a local bowyer and trading him a knife for his scraps. I am horsetrading with a bowyer that made my long bow and my wifes. I traded him a presentation tomahawk and I am working on a knife for him. So far I have gotten 4 full boxes of exotic wood and have cut the scraps into 156 sets of knife scale blanks. If you figure out what knife scales cost per pair for high end wood. I am getting a great deal for the hawk and knife.
To make things even better. The bowyer was giving his scraps to a buddy to burn because no one wanted them. He is happy the wood is being used on my work, and I am ecstatic to have a regular supply of top end wood for my knife scales.
Call around. I bet there are a lot of bowyers that would trade scrap and cut offs for a knife or two.
