As a n00b just coming into the honing scene, I feel that there is just so much information out there, it could easily overwhelm a person new to the scene. One question that I have always wanted to know is what is the difference between the brands of whetstones ? There are your Naniwas, Nortons and even some brands that I have not heard of. Does the brand matter or should we only look at the grit of the whetstones when purchasing ?
