That’s one Dale Howe made for me with some koa I brought back from Hawaii
The one Dale made for me is 3/32 thick, a little generous on length and is deeply hollow ground like yours. Good polish on the D2 on mine like yours. I asked Dale to leave the back square because I use it for separating venison from silver skin and it works like magic to give me really clean steaks when I am butchering. It looks like yours would work well for the job too.
