My apologies for not hopping immediately back in. It looks like I missed quite a bit of debate!
I decided to resolve the magnification issue before moving forward. Amazon has a Peak 22x loupe with illuminator headed my way (at a too-good-to-be-true price for a piece of that quality), but that won't be here until mid-week.
Of course, that didn't stop me.
Before reading the back-and-forth here, I decided to see what leading and training strokes would do. Well, past hopefully making sharpening a bit faster...
On getting the knife onto my 2k and not immediately feeling the edge angle, I decided to back up a step and clean up several years of what might have been mis-sharpening on my part and re-set the bevels on my Shapton Glass Stone 500. The included angle on the road is ~5* (~2 mm in 45 mm, each side) and the edge is just a hair more (probably around 8-10* total included), so the angle is still pretty steep on these. Moving through the 2k I had a decent edge on it, as well as off the 6k. I won't say a "great" edge, but I will say that the combination of resetting the bevels as well as leading and trailing strokes seem to have improved the overall situation. Sorry, I hadn't read all this so I can't call it a "controlled test" of the leading/trailing approach.
I suspect that the edge is too acute for my skills to get a "great" edge, so will be backing off a bit to see how that goes once I get the new magnifier.
I want to look at the edge before I do and along the wat for a couple of reasons:
I see a couple bumps in the edge, on one side only, when the light shines off them. The only way I can explain them is they are like a couple tiny, polished zits. I want to better understand what they are before I grind them off again.
The other is that when sharpening the knife, I would occasionally get very tiny, very sharp pieces in the swarf, definitely on the 2k and even occasionally on the 6k. I suspect that the edge is failing somehow and I'd like to better understand what is happening there as well.
I expect the loupe later this week, but I might be distracted by a FedEx box from CKTG that has a Konosuke in it that should be delivered tomorrow. Even with new toys, I will definitely check in when I have more experiences. These have been knives that, when sharp, are among my favorites both in performance, as well as just they way they feel in your hand. The balance is sweet. The handles are very comfortable for my hand, don't slip, and the finger relief on the santoku just makes me smile.
If these photos ring a bell in someone's memory with more information on these knives (or your kanji skills are better than mine), that would be welcome as well.
The 160 mm santoku is 2.65 mm thick and 45 mm tall. The 150 mm petty is 2.2 mm thick and 29 mm high. Only the santoku has the finger relief in the heel (right-handed side only). Both appear to be of sanmai construction.
Any pointers/links as to how to better at knife photography?
If anyone of you "greens" wants to "play" with these knives to see how they support or refute ideas on sharpening these alloys, I'd be happy to cover postage.
