You could make a metal clarinet your number 1 instrument for playing outdoors if you care a lot for your wooden clarinet and don't want to get a plastic clarinet. A Silver King, was as far as I know, designed for the purpose of being loud. So it would be particulari good for out-door playing. Perhaps the Silva-Bet would be a more natural choice for the 1920s concert hall in a small ensemble.:|

Do Swiss Army clarinets come with blades, scissors, can opener, etc?

I bet they do! Can tell that I wouldn't be surprised to even find a reed cutter, cork grease and pull through included too.
