I sharpened this Shun santoku this afternoon. Many will scoff at the hammered finish and metal bolster and butt cap, but this is an excellent kitchen knife. It is very thin and cuts like a dream, it is easy to maintain with Shun's VG-MAX stainless, and it is tough enough for my wife and yet easy to sharpen.
The knife came out of the block at a "food sharp" 140 on the BESS machine. I used a10"/250 mm. hard Arkansas stone to get it down to about 110. I tried a leather strop charged with 5 micron diamond paste, and hit 100. A little more stropping on that very reliable 5 micron strop got the blade down to a highly questionable 53! I'm really working on my BESS technique, but I think I may be just a few ticks away from being where I want to be!
"Old Faithful" is auction site leather on big box home improvement store plywood, all of it sanded flat. The Kent paste works better for me than the slightly cheaper Russian paste, which is the only other brand I've used. The Kent paste seems to use an oily solvent than doesn't get in the way, as opposed to the waxy carrier in the Russian compound.
This sharpening project was done freehand, using the tactile method I learned from Ricky from Burrfection. I just gently ran an edge-leading stroke across the stone until the blade (and a lot of organized practice!) told me we were on the bevel. Me and the blade, working together, like a pack of feral dogs.
I tried the angle guides I normally use to get started, and I tried the Sharpie, but I felt like I had never done this before. I put away the distracting angle guides and felt-tip pen, and it was just me and the blade and the stone. And a bottle of water with a little lanolin in it. And a towel. And a loupe. Two, well three Samuel Adams, drunk straight from the bottle. That's pretty much it. No music, you need fingertips and what little sound you get from some media. The angle guides, or Training Wheels as I called them, really served a purpose in getting started with freehand. I will keep them handy to get started on different angles on blades of different widths! A man's gotta know his limitations! Me so funny!
I can live with a freehand 100, but I think kitchen cutlery doesn't have to hit nearly that BESS score, it's probably much more useful with a more coarse edge that won't test so well.
