Side topic: is there a subforum appropriate for soliciting a knife repair job? My yanagiba came with a compound warp that I didn't notice until being frustrated at deburring for months, so I flattened it myself, which heavily eroded the urasaki. The steel is too hard to make progress with sandpaper, and I don't have access to a large grinding wheel or the confidence to apply one to this knife.

You'll get discussion in either; just posting photos with a straight edge/on a flat surface showing the complex warp and the current state of the hira, kireha, and ura is going to get you relatively quick feedback.

I'd recommend in no particular order: #1 JKI, DC Cutlery, Strata or Bernal Cutlery.

I checked recently, JKI weren't taking repair jobs. I'll look into the other though, thanks!

Thanks! Posting photos was definitely on the agenda.

So... Did you just flatten the urasaki until it was flat all the way around or did you bend / tap the knife straight first? If you're looking for a full ura regrind I think I recall seeing Bernal do something like that before but its not a procedure that is typically recommended or easily done.

Bent first. There were like three different deviations, two high areas and three low areas. Something like that. I bent it as straight as I could then ground it until it was actually flat. It's about 2/3 ura in the high spots now.
 
Damn, I would buy a proper yanagi. That should have never ever of been sold like that 🤦🏻‍♂️

Maybe we need a post where people can post what work they need and then sharpeners can reach out to posters they’re interested in working with?
 
If you're regrinding the ura, this is about how much steel you can grind away before you meet iron. Here's a cross section of a yanagi tip I snapped off, from a pre existing corroded crack. It's an old picture a couple of years ago.

My suggestion is if you want to regrind the ura, is to buy a coarse stone, and shape the stone to be convex using silicon carbide and a sheet of tile or granite or stone. Then grind the ura in. There are knife shops that might be able to do it, but it's not regular repair in the US

You can post under Sharpening Station or Shop Talk, (or for that matter Kitchen Knife) to solicit feedback on efforts to date or to solicit sharpening services. There are members here that do that kind of work. Under current forum rules they cannot promote that kind of services but they can certainly reach out to you via pm.

My first choice would be JKI - and I've been told they are taking on sharpening work again. I've also been quite happy with Toshuku, a former vendor here. Zach provides good work, good turnaround, and is quite reasonably priced.
