Hoping that you will be able to help me out. I've got an Aritsugu Santoku ( Wagokoro ) that I picked up when I was in Japan a few years ago. It is still my favourite knife ( mainly as it has my name engraved on it in Japanese
I've been sharpening it on whetstone for the last year and have recently increased my collection of whetstones, but I'm not very happy with the edge I'm able to get on it and more importantly keep on it.
I've got the following stones
240/1000 Combination stone ( not anything special )
3000/8000 Combination stone ( not anything special Grunwerg I think )
10000 Stone ( Naniwia Superstone )
Also got some natural slate stones for straight razor sharpening.
I've never taken it down as far as the 240 I usually do a progression on the 3000/8000 and recently tried it on the 10000.
I can get it cutting nicely but it doesn't stay sharp for as long as I would like neither do I think I've got it as sharp as it was originally.
Can anyone offer any advise on how to get a good edge back on it and what grit I should go up to?
Thanks for your advise in advance.
