The TID was designed by Lance Harris, a well known Security Professional that works out of Southern California.. it was designed to give you an implement for "De-Fanging" the snake, as Lance puts it.. if you wuold like to ask him some questions about it directly, he hangs out at
www.tacticalforums.com quite a bit (in the Executive Protection forum mostly). One thing that i have found interesting abou the TID is that Lance has flown numerous times (one particular trip took him from LAX to Reagan International, to Heathrow, to Afghanistan and back) and has yet to have anyone question him about it.. he takes it on every flight...
you can buy a rubber cap for the TID to keep it from eating pockets, etc..
Ive got one for my 6p.. pretty neat "alternative" impact weapon... il be getting another for my 2z here pretty soon...
the one being sold through GG&G is relatively tame by comparrison with the one that was originally designed... the first prototypes had longer, more aggressive teeth...
in my opinion its a pretty good piece of kit.. fairly inexpensive, and when used correctly (on limbs, and other soft tissue) it makes an excellent implement that offers little liability (doesnt dig all that deep) but creates GREAT pain... Nice little covert weapon..
Stay Safe and Win at All Costs!
