User Review: Victorinox Swiss Army Classic SD
Price Paid: Approximately $9
Not everyone thinks it is entirely necessary to have a knife or multi-tool on their person at all times, and a Victorinox Classic or Classic SD is the perfect knife for those people. It weighs almost nothing, and has tools that can be useful in almost any situation.
I don't carry my classic with me because I always have a larger model Victorinox in my pocket, but if you want a low-price high quality knife that will just sit on your keychain until you need it then this is the one.
