Or how about the British Army Locking Clasp Knife,

2" Sheffield Stainless-Steel Blade, lambfoot (safer than SAK blade)
Closed length of 3.75"
Stainless-Steel handle
Includes useful accessories: Tin-opener, Phillips flat-head screwdriver, and keyring for safe attachment.

Only problem I can see with this knife is if you get it you may decide to keep it for yourself. Just like the very best train sets.
