Basically they are mycarta. Resin impregnated material. Compress, let dry,sand and cut into scales,attach to knife and finish shaping. I've never seen it done with burlap. Very Cool.
Usually done with denim.
better judged by twelve than carried by six.
I don't need No stinking signature.
This is material I made using cotton canvas and colored burlap with fiberglass resin between each layer and then I compress it in a press I made and let it dry overnight. Then I sand the back smooth and it's ready to go. I've tested this stuff with a 20 oz hammer and it took me 4 hits to crack it and about 4 more to break it. It's tough stuff.
