Heres a cheap method...if ya want to stabilize your own handle material, get some wood hardener from Sherwin Williams, put on a pot of boiling water, get a large heavy duty plastic bag, pour a little, about a 1/4 can for a good set of scales, and put them in the bag with the hardener, when the water is boiling, hold the open end of the bag up and dip the bottom with the scales and hardener in it, the heat will cause everything to expand, and the scales will suck up the hardener, but first be very careful, this product has keytones in it and is highly flammable!!
dont breath the vapors and best done outside, wear your PPE, and good luck
