Micarta is a composite material made from sheets of fabric or paper saturated and glued together with resin. Although the paper or fabric may be made from natural fibers like cotton, the overall performance of micarta is that of a reinforced plastic. For example, micarta is more water resistant than the vast majority of unstablized wood species. Stabilized wood is water resistant, but if finished to a high gloss can be slippery when wet. However, surface texture like checkering, or bead blasting can be applied to the handle, and due to the increased hardness of the stabilized wood it will probably "wear" longer than an equivalent handle made from unstabilized wood of the same species before being rubbed smooth again. All this said, natural wood has been used for knife handles for centuries. Use the material that works best for you and your methods of work
