Tony, Is Flitz bad for Light, occasional use only?
My 5" 18 is not a stainless blade, so I am aware it needs to be kept clean and dry.
The handle is stainless?
The Brass Hand guards will discolor/tarnish in a heartbeat if they are handled and not cleaned..along with the buttcap.

I guess that's where the coatings come in for a real hard-use 18..like it was made for.

Or...let it show it's nicks and scars and chalk it up to "character"" like the rest of us?
