To start, I’ve got a great batch of softer suita* coming up later this week (a few may slip to next week, but they’re coming!). This type of stone is probably what I get asked for the most. Which makes sense, they’re fairly quick, easy to use, and great for polishing and sharpening kitchen knives generally.

You can expect:

  • 3 Maruo shiro suita (finally!) - one of which is a seriously cool >2.4kg renge laden monster
  • 2 Mizukihara Uchigumori
  • 2 Honyama renge suita - seriously clean, smooth, and delightful stones that won’t break the bank
And then also some mid-grits:
  • 2 Tajima - full size bricks
  • 1 Aizu - softer stone
  • 1 Kasabori - slightly smaller value priced stone
And maybe an XXXL (300x100x50 roughly) Yaginoshima asagi - because why not…

Pictures coming later tomorrow sometime I hope :)

* If soft suita are your thing, do not sleep on the Umajiyama tenjyou suita I have up already. Might not be the flashiest looking stone, but it’s pretty much the ideal all purpose knife suita IMO
 
Finally got my box of Shiros and some other goodies straight from the source, getting harder to get but finally got some stuff in.
 
Some new stuff slipped onto the site late, late last night.

Got another batch of stuff that will be trickling up onto the site starting last night and running for the next few weeks. Mostly crazy stuff on the high end.

This one I briefly cracked into last night. Sublime. Finding good, ultra-fine knife stones is a real PITA. On a good day you can choose two of the following: 1) fast, 2) easy to use (ie - won't grab and tear at soft cladding), 3) grit consistent, & 4) clean without lines. Certain Nakayama tomae, however, can give all four and when that happens it is really magical. This stone could happily finish a razor or kanna but somehow is equally happy with the larger surface area and convexity we see in knives. It's hard without feeling glassy and cuts insanely fast (relative to it's grit, this isn't going to clean up Aizu scratches lol). Only negative things I could possibly say about these is 1) getting the right layer (there are 2 of 48 tomae layers that I've tried and really loved for knives) is tricky and 2) they're not cheap.

For those of you follow the instagram page, you may have noticed I've been teasing a project for some time now. Finally ready to reveal the results!

Awhile back Ryan (@Illyria) and I were sharing some (or a lot) virtual beers and just generally chatting knives, polishing, etc. At some point while discussing wrought iron, I had a rare moment of genius and asked if he could use old, clapped out kanna blades to create a damascus cladding. Ryan graciously agreed and by morning I'd purchased dozens of worn out blades and had them on the way to New Mexico prefecture. Additionally, I sourced Aogami #1 for him to use as well.

Next the hard work began. Ryan needed to clean off the rust and sort the kanna. Then each was forged into a consistent size before creating cladding billets using 6-8 kanna each.

The result was a high layer damascus with multiple wrought irons and steels (white, blue, and even one tamahagane one slipped into the mix). Not only does this create a visually pleasing pattern, but it is immensely satisfying to give these worn out tools new life. Additionally tools are typically made from rather high quality iron and steel so the overall material quality in the billet was high as well. For this first round of knives Ryan made two variants, a twist and then a higher layer random stack.

Ryan then forged out the knives and appleid a modern HT with multiple rounds of thermal cycling, cryo-treatment, and other voodoo that is well over my head to yield something quite astounding from the Aogami 1 - a core hardness of 66.6! You may think this would be unreasonably chippy or otherwise fragile, but I've sharpened and used my example extensively now and am pleased to report no such issues! The worst I can say about this is that the steel sharpens and polishes exactly as slowly as you'd expect an extremely hard steel would.

Some of the kanna blades ended up coming with a dai as well, so we elected to continue the reclaimed theme and use the oak from the dai to create the handles as well. Japanese dai oak is of extremely high quality with a dense, consistent grain structure. Wood for dye blocks is traditionally aged for years, usually a decade or more and is therefore extremely stable. The wood ended up having exceptional grain and wonderful warmth in the hand after it got cleaned up.

I am still working on the stone polish for my personal example, but it's too good not to share Ryan's pictures.

Coming up, I'll share more about the twisted & deep etched clad version that will be available on the shop.

Goodness gracious!! Kudos to you both on this project, amazing stuff
 
I'll caveat this post with the fact that the polish will get a little cleaning up and the handle needs final install prior to sale, but I still think the product is more than finished enough to share.

Ryan has been exploring twisted claddings and deep etch techniques independently as part of his knife making journey. So we thought it would be a great idea to integrate those experiences into this blade. Prior to forging the san mai billet, the cladding bar was twisted.

The blade was forged out, rough ground, and then shaped primarily on bench stones for a mid-to-lightweight convex grind that is incredibly well balance for all tasks in the kitchen. After the shape was put in, Ryan deep-etched and polished the blades which brought out the character of the cladding and gave everything a divine texture and depth.

This is stunning
 
https://tennentoishi.com/products/honyama-renge-suitahttps://tennentoishi.com/products/honyama-renge-suita-1No one should sleep on these. Tremendous soft and easy to use suita. Depending on your taste these could be in the finisher or a "pre-finisher." I'll put them up against Maruo shiro 7 days a week and to my taste they're prettier as well. Less name recognition usually creates better value in JNats.
Prepping a knife for testing some ultra-fine finishers and used these to clean up the core steel. Once again very impressed by how fast and easy to use they are. Very grit dense and coarse (for a suita) which means there is a shallow but visible scratch pattern on soft iron but exceptionally fast at leaving a matte kasumi with no visible scratches on core steel. This is maybe 5 minutes of work after 3k synthetic.
 
Dreamy stuff. Love the handle as well. No need to overdo it. Just something simple with a steel spacer to complement the bade.
The spacer is actually an off cut from the damascus billet and should patina over time and show that more directly! And the wood is extremely high quality Japanese white oak taken from the wood base of one of the plane blades. Extremely dense vertical grain and very stable from years and years of aging.
