I'm interested in the ideas, and willing to try them out. It seems to me that people who are into sharpening razors do end up with the most direct visceral feedback of their sharpening work, and while their methods may not perfectly translate to plane and chisel blades, it's worth a look certainly. I've been trying out the CBN and diamond sprays and nanocloth strops for a while.dmccurtis wrote:I've watched that video, and Dr. Matt's others. It's intriguing, but I find it hard to draw conclusions from. HIs postulation that adding CBN to the stone catalyzes slurry break-down, and that may be, but it seems to be a solution in need of a problem. The image he shows of the non-'supercharged' Nakayama edge looks surprisingly poor, and I don't think indicative of a normal result. It's hard to tell from small pictures, but to me, it looks like the results from a stone either too hard for normal use, or too hard for its user.
Not to make things too personal, but I tend to take sharpening advice from razor sharpeners with a grain of salt. The razor community has lots of flavour of the month products and wonder-techniques, and lots of contradictory ideas about what works and why. It's even worse when Japanese naturals are added to the mix, with so little good information about them readily available.
There's plenty of info on Japanese stones in the Kezurō-kai newsletters.
