Natural Whetstones

I made these whetstones to sharpen my tools

two rocks or more that you would like to make into whetstones

Look for some nice flat stones that are the shape/size you desire.

Leave the stones fully submerged for five minutes (Important!).

Grind the stones together until they are flat

polish the stone against each other to make a stone that will make a scary sharp edge (If desired).

If you have followed all of the steps to here then you will have some natural sharpening stone.
