Caring For A Knife:

Caring for a knife is very easy.

Simply rinse the knife with water, hot or cold is doesn't matter; or blast it with a water nozzle.

Then wipe it off with a paper towel. Leave it air dry.

Once the knife is dry put it back into the sheath.

 Simple - Done.

*** Never put a custom knife in the dishwasher! *** 

The high heat may cause deformation and separation of the handle.

I'm not saying this will always happen but it could.
