Iuse a 4 stone lansky and a lot of leather I have my best luck with buck knives. Take your time #1 get your rough cuts good and even and polish that edge like a mirror starting down the the line of stone rough to smooth The more time you send with the last stone and leather will pay off. You will know its right when its pulling the hair on your arm. I love sharp knives and I have a bunch Have you ever used 1 that you can change the blades?
