so guys ive got a little situation that im unsure about, today i went into work with a recently purchased moritaka petty and decided to test it against the breakfast juice prep which involves about 20kg of oranges and 20kg or grapefruit + a bunch off pears, pineapples, apples, and watermelon. knowing that this blade is AS and carbon of course i knew what would happen slightly but wanted to see for myself. this is all on factory edge btw just didnt have the time to put my own edge on it until today after work as ive been busy. so basicly after about 10kg off cutting oranges for juicing the blade started to heavily patina, mostly dark greys slight blue tint to it, so i kept on prepping i should point out i was really giving this knife a workout. once i finally got onto the grapefruits it started to patina even more and it actually let off a really strong metalurgic smell and started to gain very dark brown colour im thinking it was just light rust but possibly patina. then the kuri ochi finish on the blade actually started to come off in spots and edge retention died a little bit not much but you could feel it dull a little maybe it was just because the oob edge was horrid or the acidity not 100% shure.
so after work i took it home took my rust removal paste and took the dark brown colouring off i managed to leave some patina and then i sharpening it up and stropped it and gave it a little test the edge is beyond anything it was before and the blade looks alright again but some off the kuriochi finish on the tip end is gone and alot off it is worn down.
now my real questions are, if i continue cutting citrus with this knife will patina form ok and if it does will this stop the metalurgic smell, or will it slowly eat the metal to much from my blade and cause continuous rusting. i am wiping the blade alot and washing it off through the whole process.
and before you ask why dont you just use a stainless petty well i have a decent stainless honesuki i love using for it but what im wanting to know is how my blade can handle the prep
