One of the latest upgrades to the ViperSharp Professional Guided Sharpening system is the heavier Stone base option. The base is 6 inches squared with one corner cut. It weighs approximately 2lbs 5oz and offers great weight to keep your system steady without the need of a clamp or screwing it down.
The stone base will come in an off white speckled stone color similar to what is seen in the image. Some color variation will occur since we are using natural products for this base.
If you are upgrading to the stone base with a system shipped before December 2017 you will need to send in your upright assembly that fits into the base. It will be replaced with a new assembly that will work with both bases.
