The Tucson police have release some 600 images taken in the aftermath of spree killer Jared Lee Loughner’s attack on a rally for Congresswoman Gabrielle Giffords. Included in the photo gallery: the knife Loughner carried during his homicidal frenzy. It’s a Smith & Wesson Extreme Ops. Smith doesn’t offer the knife in that particular blade or handle shape any more. The current $24.95 Extreme Ops is fashioned from titanium coated 420 stainless steel with a black G10 handle. It’s imported from China.
