Full on rusting is a different thing to a little spotting and tarnishing.It is quite hard for a knife to become totally rusty if you take just a little care.Even though I use mine in all weathers the most I get is a little spotting with rust and this either rubs off when I oil them or comes off the next time I use them for battoning !
I actually like to see a few spots of rust first appear as the knife is then tainted and I don't worry about using it ! To me it's the same as with my cars, I hate it when they are all pristine and new because I'm always washing them and worrying about where I park them. Once they have their first supermarket cart scratch it's great and all that worry is taken off your shoulders !!!!
