Warranty suspended due to going out of business. I’m one man. I’ve been running ViperSharp since I created it in 2015. The viperSharp is a great product and I’ve had very few (less than 1/2 of 1%) issues with manufacturing and the performance of the product. Since I have chosen to stop producing the system to move on to other things, warranty issues will be limited to stock left on hand. thank you for your understaning and support.

The ViperSharp knife sharpener is a professional precision sharpening system that will allow you the precision you desire with every blade you sharpen.
