Itto Ryu reactivity

Sat Nov 30, 2013 4:48 pm

I just received my

Itto-Ryu Rentetsu Hand Forged White #1 Santoku 160mm

Knife within the last two weeks. It is starting to rust despite careful use and storage. What should I do?

Hi Deblina,

It's made with carbon steel so it will rust if you don't keep it dry.

Get some stuff called Bar Keeper's Friend and scrub the knife with that if you get any rust on it. Then just use the knife, wash and dry and it will be fine.

I got to meet this blacksmith in May. He has his shop in the middle of the woods on his property. It was a really special experience and he's a highly skilled smith.

Kind Regards,

Thanks Mark. I'm having problems with it rusting as I'm cutting large jobs. Why is it rusting so fast?

The iron on the exterior of the knife is reactive. Once the knife gets patina on the blade (it will turn grey and black) the knife won't be nearly as reactive. Using Bar Keeper's friend will help since it's made with an acidic abrasive powder that will remove rust and oxidation.

Also, you can quickly force patina on the blade by using mustard. Just dab mustard on the knife and let it sit for about 15 minutes and then wash it off. It will quickly turn the knife dark and that will lessen the reactivity you are experiencing.

OK, I will try the mustard and see if that improves things.

Thanks Mark. The mustard did the trick!
