Rust in the kanji

[loganrah]

So the stamped kanji on my new TF cleaver appears to be rusting. I presume this means the kanji is stamped deep enough to get into the carbon steel in the core? Is this a problem? And is there any good way to prevent this rusting further.

It is possible that water is staying in there after washing. Try using very hot water to rinse. The residual heat will cause the water to evaporate quickly. For the rust I've had success cleaning it in similar situations by using chromium oxide on something soft that I could work into the kanji. I've also used metal polish with some success but be careful putting chemicals on something you use to process food. The Tad is probably clad with stainless which is why you're thinking the stamp is to the core steel but stainless steel can rust under certain conditions. The most common is lack of chromium and other stuff can happen with chromium at high temperatures (like in a forge). Unless there is a larger degradation I wouldn't worry that much about it. It is possible that it will oxidize and stabilize over time. You can ever leave the rust there to see what direction it takes. Hope that help you out.

u'll be fine, it's likely just superficial rusting/patina. I have some on my Denkas.

Try some Bon Ami with a stiff toothbrush (cut a few mm off the bristles for extra stiffness). Oil and a tiny bit of wax will protect it.
