On the list was “Kershaw assisted opening knives.” These would be the ’speedsafe’ variety, like the Ken Onion Chive, Leek, etc. I didn’t have it with me that day, but I own a Chive. (They’re under 3 inches blade – more a pocketknife than a Buck folder.)

Anyway, I can understand why they wouldn’t want knives in the Memorial. (Even though it looked like a 2 inch regular penknife would be fine.)

But can anyone point to where the Kershaw torsion bar blades have somehow been outlawed Federally? Kershaw used to make the point that they were PERFECTLY legal to own (i.e. not a switchblade, not a pushbutton stiletto, etc.)

Thanks for taking the time to look!
I appreciate the answers. It will be a hard best answer choice. The consensus so far is that it’s perfectly legal by Federal law. I rechecked Kershaw’s website, and it still says in the FAQs that SpeedSafe is perfectly legal.

Clarifying my question: I am SURE that I read the sign correctly, and that it stated that SpeedSafes are NOT LEGAL to carry into the property. (It was listed with Butterfly knives, Gravity knives, Switchblades, and other knife types. And I know switchblades aren’t legal.)

I do know a property owner can prohibit whatever he or she wants. If a 7-11 doesn’t want you to carry a box cutter into their store, they can deny admittance / ask you to leave / deny you service. But it would surprise me if the same principle applies on Federal property – I’dve thought they need SOME justification in law to post such a notice. And, at any rate, the notice said such are illegal.

So does anyone know what law would allow them to say that regarding SpeedSafes?
