Howdy there

As stated above making sure your stones are FLAT. One problem with the Norton 4k is how soft it is. Sence Hinkles are soft steel anyway you will not have as much trouble as I do. I can feel the 4k stone grinding away from my Hiromoto AS knives.

I've started using my razor on the stones first, than going to the rest of my knives. That way I only have to flatten once. Razors don't erode the 4k side enough to worry about.

Feel free to ask any questions you have
