Live blades can have an aluminum trainer made for an additional $30 on top of the price of the blade. Over-sized live blade trainers will incur slightly more cost, due to the extra material necessary. They are made from 6061 aluminum and come with smooth edges, no hot spots and a brushed finish.
When purchasing a blade, please inform me if you want a trainer before I ship your order. It usually takes me a day or two to knock out a trainer.
