The guy i talked to for helo finding the right stone was super heloful! I wish I remembered his name. I think maybe steve. I went way down the rabbit hole trying to find the right water stone. It was my first one and it’s perfect. Its made sharpening so enjoyable and less intimidating and my chisels amd plane irons are working at a level i didnt know existed. Thanks! Picture after about 4 hours of sharpening and 8 chisels cutting through end grain of hard maple like butter!
