All TAK Training Knives & Swords (except Compressor series) are made from polycarbonate. We use 3/8" thick material which gives a wider striking surface to displace impact force.
What are the Benefits of Polycarbonate? Outstanding impact strength! No other thermoplastic comes close to matching the impact strength of polycarbonate, making it the ideal material for TAK Training Knives & Swords. You can wail our swords against a hard pell 110% all day long and the sword will win!
Here is an excellent video from National Cycle demonstrating their superior polycarbonate windshields. Keep in mind that these windshields are only 3/16" thick vs. the 3/8" material we use on TAK trainers!
