Yes, that is Alex Gilmore.

I first started using the Jointing technique, as a result of my interpolation of Jim Rion’s translation of Kousuke Iwasaki’s, 1963, Honing Razors and Nihonkamisori.

You also might try stropping the razor prior to the final stone, also recommended by Iwasaki, on Chromium Oxide. I use a Polyester canvas sailcloth strop, Alex uses leather, both work.

The stropping does a similar thing, though not cutting off the flashing, it does align and polish the edge, prior to the final polish on the finish stone. And to me does make a difference in the edge.

Alex a member here, also has many excellent videos on his website The Japan Stone.
