Thanks all for the advice. I have sharpened my first 2 knives today at 20 dps . They have turned out quite sharp but I know I need to improve my technique. I’m not sure if the knives I have would be classed as hard steel. I have a few Global knives that are marked as G-2 , some elite knives marked as 57 HRC AND 1 SHUN knive that says DM 0707 cobalt. I know this is a layered one that is extremely hard . Am I ok to use the diamond stones on the shun knife and are the other global ones and the 57 HRC ones classed as medium or hard steel. Thanks again for any advice you can give.
Regards
Steve
