I have a lot of carbon blades in the kitchen, they will patina, but how depends on what you cut and how you look after them. Onion will quickly leave dark blotches if you leave chunks sitting on the blade, as will leaving it sitting in lemon or other acidic food juices. I don't find rust to be an issue unless the blade is left wet overnight(ish). I'm in Melbourne though, NT / QLD may have different results.Does anyone here own or use a carbon steel cooking knife?
What kind of knife/knives do you own? Did you force a patina or just let it develop over time?
The reason I ask is because I'm attending a knife making workshop in Sakai, Japan (just outside of Osaka) and assembling my own carbon steel knife!
So basically the blacksmith makes the knife blade/tang, then I get to knock the handle on and learn how to sharpen it.
I also get to choose six characters to stamp into the blade![]()
The knives my wife (ab)uses end up with uneven dark patches and rust spots from not being cleaned immediately and/or put on the rack wet. I've given up caring, so just keep these sharp. I tend to wipe, rinse and dry straight away so my "good" knives have developed a milder more even patina. I've done a forced mustard patina to meh results. Coffee works to darken the blade but your surface prep needs to be spot on otherwise it gets streaks and blotches and looks shit. It'll also show up inconsistent heat treatment. It's really a lot of fuck around when it doesn't work.
Patina can be removed with scotchbrite and / or autosol. However, getting a decent finish takes a bit of work. If you are going to rub the blade, angle the edge down against the surface so it's protected from stray fingers ;-)
Have fun with the course.
