You can buy left-handed scissors, left-handed pens, and left-handed can openers. Life is good these days for left-handed civilians. But what about 
left-handed soldiers? Enter the ET-MP:
Unlike traditional grenades, the Enhanced Tactical Multi-Purpose (ET-MP) hand grenade is designed to be thrown with either the right or left hand. “Current grenades require a different arming procedure for left-handed users,” said a statement by the US Army.
It’s about damn time. And speaking of lefties, I was chatting with a left-handed friend the other day and he said that the final frontier for southpaws was cameras. Everything is on the right, and needless to say, nobody makes left-handed cameras. Even after decades of using cameras, he says it’s still a pain. Do other lefties concur? And how expensive would it be for Nikon or Canon to gear up the injection molding for a lefty version of a few of their cameras? Maybe they could corner the market.
