The new Ultra Light series of Blazer augers feature an innovative nylon composite blade mounting bed. This reduces the weight of the auger by 10% AND results in less blade breakage due to expansion and contraction of the materials under temperature extremes. ThunderBay products are designed for years and years of use in the harshest of winter conditions. Your new ice chisel is backed by a two-year warranty against manufacturer defect and customer service is just a phone call away at 855-691-5969.
