Anybody have any idea how to cure the slippery feel of my XL Paragon? Knife is pretty old, bought it when they first did a rev. in Fighting Knives Mag. Just dug it out once again and actually a great knife that doesn't get carried due to slippery handles. So outside of totally re-doing the handles what does anyone suggest I can do to the handles to make them less slippery feeling. thanks and keepem sharp
