Here's a sweet knife my brother pointed me to, the Gerber Military Tactical LMF II - A.S.E.K. Knife. I love knives, but before buying this one I'd better read up on Missouri's knife laws.
Hm, the statutes seem to indicate that knives more than four inches in length are treated as "weapons", whereas there are no prohibitions on shorter blades. However, the page also indicates that courts have enforced weapon rules on shorter blades and even butter knives. The LMF II has a blade that's almost five inches long, so it may not be the right thing for me to get unless I just want to look at it.
