Camp10 recently did a video on a method he uses for stabilizing knife handles. It's a method that is simple and can easily be done (following proper precautions) by anybody.
Here's a view of the method I've used. The equipment belongs to my mentor. It's amazing what a little backwoods engineering can accomplish.
The material to be stabilized is placed in a heavy (bomb proof) cylinder.

The cylinder is then placed under a hydraulic ram.

The material in the cylinder is placed under 3500 psi. The hardening material and dyes are placed in a vacuum chamber and the liquid is introduced into the cylinder (without breaking the vacuum).

After an hour or two, the material is removed from the cylinder. The hardener and dye have gone through every pore in the material (stabilizing), making it very hard and impenetrable to liquids.
This is just one thing that makes knives (or at least the handles) cost a little more.
