"You know the blade can only be as big as your four fingers right?"
(I pull out my knifeup.com bookmark on my phone) "Read this. Read all of it"
I actually saw an episode of COPS, an old one, from Florida, where the officer being shown actually said that to the camera after the guy he arrested was carrying a knife. He held up his hand next to the blade (which was longer) and said that the four fingers rule was the law (...facepalm...)...that's like the NYC "gravity knife" definition and test where they hold it by the blade and shake it...I don't practice criminal law, but that test is just begging to be challenged like many field sobriety test methods have been over the years (and why even accepted ones are constantly being ruled inadmissible, I have a couple friends who do DWI defense and are more than a little proud of their success rates at suppressing FTSs).
If one had inch wide fingers then they either need to A)lose weight or B) seek treatment for Elephantiasis!
