Tojiro ITK highly reactive?

Thu Jul 26, 2012 5:04 am

I have been using for a few days now the ITK petty and kiritsuke. Has anyone else felt that this is a highly reactive knife? I havent had an issue with rust or anything but have noticed it is WAY more reactive than my fuji carbon gyuto. As the patina builds will this slow down? Also if this helps with other responses. I am new to carbon knives, so my "highly reactive" may not be what you consider highly reactive. Thanks for all the insight and future info shed on this topic.


BTW I love the edge of a carbon blade compared to SS!!!! Im sold on carbon no matter how reactive a knife may be.

Howdy Drew,

Yes they're very reactive on the first use. If you force a patina on them it will greatly reduce the reactivity on them.

Thanks Mark, I polished the finish right when I got them and forced a patina. It helped but they were still very reactive. So i forced a harder one and that seems to be helping a little more. In time it will get better!

Did you remove the Kurouchi finish?

I've also got one of these knives and, man, do I love it! It's my first knife in white steel and it takes the sharpest edge I have ever been able to get on a knife. In fact, it now shaves more comfortable than my best straight razor. And for the money it is a true bargain.

It is very reactive at first. But after polishing it (with sandpaper up to P2500) and letting a patina develop, it's much less reactive. I let the kuro-uchi on. I like the looks and it doesn't hinder when using the knife.

Incidentally, the knife is hard. I managed to break the tip off. But I must admit that what I did doesn't qualify as "normal use". If you're curious, here is how I managed to: http://moleculepolishing.wordpress.com/2012/08/12/554/
