After disarming for a Blazer game last night I've decided I need a knife that will go through the metal detector. Ceramic? Carbon Fiber? Any suggestions? BTW I already have two plastic flasks that I brought to beat the high cost of beer at the Rose garden ($9 dollars for a beer) They worked well and I had several people ask me where they can get one. I don't want a cheesy molded plastic knife, I want a real knife that will pass through a metal detector.
