This combined with taper grinding, progressive teeth, new Electroless Nickel Plating (ENP), and Silky’s patented dual roller locking mechanism results in the fastest and smoothest handsaw of its size. The ingenious design of the GunFighter’s progressive teeth makes for easier starts to each stroke, while still taking advantage of larger, faster cutting Silky teeth. So, the job gets done quicker and you are left with more time and energy for other tasks.
