    Default Iwasaki Kamisori Edge Restore

    This is the follow up honing from this thread Iwasaki Kamisori Repair/Restore
    I thought it more appropriate to post here as I have a ton of pics (30+) & this is a bit more of an advanced honing topic.

    I think it'll take me about 10 or so posts to lay out all the pics. Hopefully it all flows together ok.
    Lots microscope pics too.

    Ok so this is all post cosmetic restoration.

    Decided to set the ura (back) first. Wanted it fine & small so used za sto-orn I got last November. When So, aka Japan-tool moved up the north coast he dropped it in for me & I've been learning it ever since. It's a very aggressive but very fine Yaginoshima Asagi. I haven't shaved off it yet but it's on the cards. It was from So's collection & came from Hatanaka san but maybe I'll review it another time. Gotta type this honing up while it's fresh in my mind.


    First 2 pics are bevel near toe. Ura (back) first,some micro pits above the bevel. Omote (front) second. Nasty pits within the bevel

    The Y. Asagi with slurry created using Atoma 1200. Up & down the stone about 4x doing short back n forth strokes counting to 20 in each direction. Kinda like circles but in a straight line Quite happy with the bevel that formed & the short time it took.

    Onto the omote (front). Not so fast. Same stone & slurry with some Iyo slurry added for more aggressive cutting or so I thought


    Plenty of muddy metal & razor sticking to the hone but too slow to clear the pits . Another odd thing the razor starts rusting as I hone . LOL.. All too slow & inconvenient so got the Ha no Kuromaku 2k This is the J. Shapton Pro but I'll call it HNK for brevity. Used the Atoma 400 for a bit of slurry & went for it
    Set the bevel & cleared the pits in no time maybe 2-3x up & down the stone. A burr formed so fast I missed it happening. M'scope pics show the burr & how they sparkle in the right light. Last pic is at top end of magnification. Used a glass same as I would use my thumbnail & then moved to 5k. I just realised my fingers made bamboo trees in the slurry... I'm easily distracted sometimes

    Decide to go back the Y.Asagi with a light Tenjyou slurry this time. Now memory gets blurry but I think I did 30 on this light slurry & a few on the ura for balance.
    Pic is also a bit blurry but shows the slurry on the blade. Followed by 2 m'scope pics at different light.
