So I was thinking about getting some freehand stones because I'm pretty good at keeping a consistent angle and don't have the money for something like an Edge Pro Apex. I like there stones because they're only like 8.00$ each and I was wondering if they are high quality and if you recommend them. I was going to buy the 400, 600, and 1000 grit stones. For those stones is there any specific procedure (like water or something.)
