USA - Quick summary of knife laws

OFF THE WIRE

by Carl Donath
After following rec.knives for a while, it became obvious that a quick summary of knife laws would be handy. Here's what little I've been able to glean from my reading.
My goal is to find the clear portion of what is flat-out legal and easily summarized. I realize most states confuse the issue unmercifully; I'll let others figure out how to push the limits.
WARNING: This document is created from hearsay and whatever laws I could find. For legal advice, ask a lawyer. I could be lying. I only provide this to try to slightly improve the general lack of information on this subject. YOU are responsible for your own actions. If you don't know exactly what the laws are for any state or locale you are in, GO FIND OUT. (http://www.ncsl.org/public/sitesleg.htm is a good start, containing pointers to all state legislative sites.) I haven't updated this for a while, so consider it a cursory guide.

Explaination

State (hyperlink goes to detailed explaination)
  • Summary:

    • Basically, I want to answer the question "I'm flying to state X tomorrow, so which knife can I take?"
  • Max length:

    • Size limit, measured the most unpleasant way possible. Some may permit longer in certain cases, but I won't suggest anything longer if it's in a gray area.
  • Specifically illegal:

    • Specific styles which are explicitly forbidden.
    Switchblade = Push a button/lever, it does the rest.
    Gravity knives = Opened by gravity or centrifigual force. Butterfly knives (balisongs) included.
  • Relevant laws:

    • A quick pointer to roughly where the relevant laws are (ex. Penal Code 642)
  • Quirks:

    • Dark humor points (ex: a 1" lockback in a pocket is illegal, but a 15" Bowie swinging free is ok)
  • Local restrictions:

    • City/county restrictions.
BTW So many places forbid sharp things in schools that this sentence is the only place I'll mention this: assume posession of knives in schools - even colleges - is illegal.
Use this as guidance: kids have been suspended for mere posession of nail clippers.

US Knife Law Summary

  • Ballistic knives (automatic blade throwers) are prohibited.
  • Switchblades may not be transported/mailed across state lines unless the recipient intends to use it for military use.
  • Possessing a knife in a federal facility is prohibited unless it is a pocket knife with blade under 2.5".

State Knife Law Summaries
