The Victorinox Companion SD is a retired, very compact keychain knife with a smooth aluminum body. It is similar to the more common Companion, but with a screwdriver tip on the nail file instead of a rounded cleaner. Victorinox seems to have released a few of this model right around when the Companion was retired. It's possible that they just ran out of old-style nail files, before they ran out of Companion scales!
There are no similar Wenger or Leatherman knives.
