After each use, the knife blade (and any other parts) should be thoroughly cleaned and, if necessary, lightly lubricated with oil to keep them in perfect working condition.

When storing knives, they should not be kept in damp or dirty environments. Knives with open blades should not be stored in bulk or together with metal objects to prevent damage, dulling of the blade, or injury during handling.

If a knife will not be used for an extended period, it should be thoroughly cleaned, preserved, and stored in the open position to prevent excessive strain on the ejection springs. Complete instructions for replacing the ejection springs can be found here.
