Hey everybody, I’m looking for some tips on forcing patina on a Spicy White Heiji gyuto. Thanks for the input family. John

Cut some pineapples, those make your patina go dark very quickly.

Or you can dip it in cheap coffee overnight.

Meat juices.
Cover liberally.
Forget the knife on the counter/cutting board because you're hungry.
Remember knife.
Rinse off under hot water.

This is after 2 hours in coffee.

That's pretty nice for a coffee patina. Mine always come out grey.

I tried to force patina into a Steelport yesterday with some Coffee Luwak Pourover on Kalita wave. it turns some of the blades into Blueish purple colour.

an expensive coffee just to try a forced patina.

Cheap instant coffee works good. Nice and acidic.

Yeah we don’t have those that time. Since we never drink ****** coffee, and those are leftover. Next time I’ll try with instant coffee

I'm not a huge fan of coffee patina though it does smell good. For blues, meats do a good job and also fresh ginger as well. Prepping a batch of Chinese ginger scallion sauce will give you some nice color.

Alternatively you can cheat like this

Although the coffee patina (I use really cheap instant coffee for this task and I make it extremely strong) produces a rather blah patina, I would say that it is quite effective. The patina is pretty durable and it does seem to protect the blade. I've force a patina with mustard before, too, and it works pretty well. Mustard, though, also produces a less-than-spectacular patina. At least on my knives.

I haven’t gotten as deep into this as some, but of everything I’ve tried both accidentally and intentionally cutting a bunch of meat is the best. Beef > chicken but chicken is better than onion, lemon, tomato, …
