    before and after of custom takeshi saji gyuto (a lot of thinning, adding of distal taper, and refinishing)...

    Takeda after thinning:

    (side by side with an untouched takeda... not the same one, but i forgot to take a before pic, and the bevels of the thinned one were actually smaller than the one i pictured on the left for reference)...

    [​IMG]

    and some more pictures of the takeda after thinning (and etching for fun)...

    Wow Jon, that's quite the transformation on the Takeda. I can't wait to see how the one on the left turns out ;)

    On can actually see that you did distal taper on the takeshi saji gyuto - the damascus pattern changed. But should not one actually call that 'advanced stock removal' with that amount of work done? :)

    That choil shot of the Takeda...wow!
    Go back 2010 or around that time, is that what his grind looked like OOTB?
    Jon is the go-to pro for thinning. No way I could do this on stones, alone, without
    ending up with a zero grind and no convex.
    Could someone with an early Takeda's post their choil shot for comparison?

    Jon,
    A hallmark quality comes across in this choil shot...flexible but sturdy. Only in what I've read, but it makes sense when looking at the grind. Have metal in all the right places, and leave out where not needed.
    A few days ago, I made an order to Shosui. He promptly responded. I had found this photo on line and used it as an example. Shosui makes a very favorable impression of wanting
    to please. I don't mind having to wait the customary period when making a direct order. The hard part is calming down from sheer excitement, and toes crossed about expectations.
    Thanks for the postings on the Takeda.

    after handle and saya cleanup and some sharpening to get this set up for initial use (we do this kind of work to all of the Jin knives we sell when we sell them, unless the customer requests otherwise)...

    more takeda stuff (i've got about 4 more to get done this week still)

    after thinning, applying a black oxidized finish to replicate the look of KU, and etching the edge (i hadnt sharpened this one at the time the picture was taken... i took it to demonstrate the finish in a different thread).

    and a choil shot:

    Jon, when you're thinning the Takeda's, are you just using the same technique you demonstrate in your thinning video? Or are you doing anything else to deal with the shoulders?

    Same stuff... Different tools (I use a large water wheel). Also, shoulders aren't really an issue at the acute angles I thin at, but they are still there

    Thanks Jon. Out of curiosity, why aren't shoulder's an issue at acute angles?

    A spine is a shoulder at an acute angle.

    Same reason this makes sense and makes me laugh a bit:

    Shoulders become an issue when they cause excessive pressure to be exerted against foods and wedge... when the angles are more acute, this doesnt really happen. If the thinning was a bit less acute, the top of the thinning would still be thick enough to cause wedging, and smoothing over the bevels would make more sense.

    That's gorgeous, I just checked DHL and it looks like three more mirror polished blue #2 honyaki have arrived ;)

    Although they aren't as pretty as this one.

    finishing up a shigefusa mukimono today (well, i have the back to do tomorrow, but almost there)...

    After a lot of hand sharpening and polishing up to an almost mirror finish (and with a mirror finish along the entire bevel), we used finger stones to polish and create contrast
    [​IMG]

    The result along the edge... the rest of the knife has not yet been polished
    [​IMG]

    After polishing the rest of the knife... we use different stones and powders than we do with the edge, so they dont all blend together and look uniform
    [​IMG]

    Another view (and semi-selfie i guess)
