Combination Sharpening Stone harbor freight has them

kidwooh86 kidwooh86 depending what stone you get. There’s oil stone, water stone, crystal stone, etc

You can use water, oil or even dry. The use of oil or water is to help keep the spent metal in suspension. Now dont use oil on a waterstone or water on a oilstone that already has been treated with oil unless you degrease it. I have several of the Harbor Freight two sided cheap whetstones I use water on. Buy 2 and use oil on one and water on the other. See the difference.

Amateur way of sharpening blades

kidwooh86 kidwooh86 that’s what I thought too

Of course it works. Its a sharpening stone and it sharpens. Your barber is giving you wrong information

Ok
