Will a Saya accelerate corrosion?

Fri May 09, 2014 8:00 am

Hi All

I recently received three knives, one Petty, one Gyuto and one Nakiri all in AS steel
The Petty and Gyuto had Sayas, the Nakiri didn't.

When I opened the package I could see that the edge on both the Gyuto and Petty had started to corrode (probably due to the humid climate in Bangkok and the long time they spent in customs). But to my surprise the Nakiri was clean.

Thus my question, will a knife with Saya corrode faster then a knife without a Saya?

If the knife isn't fully dry, it can lead to discoloration/rust. Most knives not in sayas ship with an anti rust paper wrapped around the blade, too. Changes in temp/humidity can make moisture form of the blade and if it's in a saya, the moisture has a harder time escaping and can lead to rust.

unless the saya has moisture in it, it won't accelerate the process. bangkok isnt only humid, but theres a high level of salt in the air, both of which speeds rust and corrosion. carbon steel knives are much harder to maintain in this environment, but the same rules still apply. wash your knives well, make sure you dry them impeccably and if you're not using them for more than 3 days, coat them with camellia oil
