So how does the batf decide really what is class 3 or not?  Here is my thing.  The same guys that bring you the stinger pen pistol (Non NFA) have a version that is basicly a folding pocket knife.  It is OK for every body.  However the really cool bayonet with the 6 shot 22LR revolver built in is class 3.  I would think that the stinger is more dangerous due to the fact that it is a size of a pen.  But no the k-bar sized knife revolver is restricted.  Just who decides this and whats up with that?

The revolver/knife doesn't require any reconfiguring to fire.  The Stinger "pen gun" has to be folded into position before it will function while a NFA pengun will fire as is.  Same for beltbuckle guns, the NAA beltbuckle revolver must be removed from the buckle first to be used as a firearm while the old Nazi beltbuckle gun was meant to be fired from the waist.  Wallet holsters & HK briefcase guns also are in the same category.  If the concealed gun can be fired "as is" then it's a AOW.

It is somewhat subjective - if it "looks" like a traditional gun when fired, then it is a title I firearm.  If it is "disguised", it is NFA.  Since the stinger needs to be folded to fire, and forms a pistol-like shape, it is considered a title I.  Same with the folding knife.  However, Since the fixed blade knife gun looks more or less just like a knife, it is considered NFA.
