Your knife has a stainless steel blade (12c27 Sandvik Stainless steel to be precise). The blade will not rust, however try to avoid leaving your knife in damp environments for extended period of time and dry the blade after each use. The handle of your Opinel knife is made of wood, as you can only assume wood will expand and contract with humidity and to much of it may temporarily affect the mechanism of your knife. We strongly suggest that you take a look at our F.A.Q where most common questions about Opinel knives are answered.
