polymer (p l -m r) Any of various chemical compounds made of smaller, identical molecules (called monomers) linked together. Some polymers, like cellulose, occur naturally, while others, like nylon, are artificial. Polymers have extremely high molecular weights, make up many of the tissues of organisms, and have extremely varied and versatile uses in industry, such as in making plastics, concrete, glass, and rubber.
I like polymer for most of mine. Two reasons if I modify it and mess up replacements are cheap. It resists oil better than wood, sometimes i get heavy with the oil bottle.
Wood looks good especially laminated stocks, but deep woods off will rip into a wood finish like a hot knife through butter.
