so i took these blue tanakas to the stones today, only down to 1000 then finish on synthetic aoto (very little on this one) strop with cbn (cubic boron nitride) spray, and i dont know if i was doing something wrong but there were long strips of wire coming off the blade with very little pressure applied. this is the sharpest edge i've ever ended up with, kudos to blue carbon steel!
did the vinegar bath on the 210 as well, but only 2 dunks of 5min each this time and the results were much better. then tried to patina with hot chicken. after scrubbing off the gross brown stuff ended up with mild blue/green/yellow colors. the acid patina thing really does offer some protection from reactivity i guess. cleaned and sliced quite a few brussels sprouts with the petty and left it there for 15min with no reactivity what so ever.
