Hello my name is Chris Williams, thanks for checking out my products and website. I served 20 years in the US Army in the Spec ops arena. By the way Im the guy in the center of the photo with no helmet on. I created this grinder because in 2010 I was very displeased with what was on the market, I developed this for myself and before I knew it all my friends wanted one. I quit my job and went fulltime being a knifemaker and grinder manufacturer. I am a one man shop that strives to make the best tools on the market. Thx for checking out my products.
