The two main products that you will need insight on with regards to sharpening are our 2 Blade and 3 Blade models. Our 3 Blade model is one of the simpilist products to sharpen on the market. This model can simple be laid flat on a sharpening stone and sharpened by passing each of the sides through different series of stone grits. We also recommend finalizing the sharping process by using a leather strope to hone it in as a last step.
