    Hi- reposting to main forum to hopefully get in the right place.

    Lord help me, but WE has inventory (shhhh, don’t tell anyone.. yet please) and I’m about to pull the trigger but want one last set of eyes on this and hope for LOTS of feedback.  (Yes I’ve been reading a LOT on here and watching YouTube etc….).

    Sorry but this will be a long post.

    My question is, which stones / kit  to get to kick this off?

    I’ll be generally maintaing already sharp edges on this kit and am not worries about the cheap beater cleaver that I can easily sharpen freehand on a battery of whetstones or diamond plates or even a 25 year old Tormek (big green one) – which can / is / will be used for MAJOR work .. aka that friend who has a knife never ever sharpened or horribly chipped.. You know your “friend” who’s  has those Henkles for 20 years, cuts on a glass “cutting board” and didn’t know knives could be sharpened?

    I realize, or have read many comments (Thanks in advance MarcH, TcMeyer and others) that diamonds can be / are problematic on certain steels  ~ >60 Rockwell (generic statement). I’ll put together a kit list below including both direct WE products and three Shapton Pro Kuromaku Stones Pack for Wicked Edge (again – MarcH find / recommendation). I’ve read some contrarian opinions that low-pressure, edge leading strokes starting at 1K is not problematic. I want to try stuff, but not break the bank (this kit will soon be more $ than most people spend on three generations of knives for three generations of family).

    So, I’ve got a mix knives. Kitchen and folders. I’m “very experienced (25 years +-)” on whet stones but only as a home sharpener so I wouldn’t call myself an expert by professional standards. My current arsenals of whetstones starts at ?200 and goes to 10k. UltraSharp diamond plates ~100-1200, a very old Tormek (non-Japanese wheel), a paper wheel, and lord knows what else has been tossed or  is sitting in the back of  shop-cabinet / drawer.

    My biggest “concern” is my very hard Japanese kitchen knives as well as some of my folders actually. I’ll list them out below, but my biggest concern is the super steels or super blue’s; I think??? HELP PLEASE.  If anyone has specific experience on any of these steels or blade geometries PLEASE ADVISE.

    Help me choose the right kit please.

    Knives I own:

    Here is a list / Bill Of Material / Shopping list but I’d like to perhaps pare it down (save $) if reasonable and still get me some knives with a bit toothy edge but many that’ll be silly sharp.


    Are 12″ rods the right size for 420 mm Gyuto on the raiser?

    Does the range of shapton feel right? Again, any “deep work” will be few and far between and I have the Tormek or Diamond plates as options.
