[Source: 9/11 Commission]Several 9/11 hijackers purchase multi-use tools and small knives that “may actually have been used in the attacks.” according to the 9/11 Commission. [9/11 Commission, 7/24/2004, pp. 248-249]
bullet On July 8, Flight 11 hijacker Mohamed Atta buys two Victorinox Swiss Army knives at Zurich Airport, Switzerland, while on his way to Spain (see July 8-19, 2001). He possibly attempts to buy box cutters in Florida on August 27. On August 30, he buys a Leatherman multi-tool in Boynton Beach, Florida. [9/11 Commission, 7/24/2004, pp. 530; 9/11 Commission, 8/26/2004, pp. 4, 85]
bullet On August 13, Flight 175 hijackers Marwan Alshehhi, Fayez Ahmed Banihammad, and Hamza Alghamdi buy knives and multi-tools. Alshehhi buys a Cliphanger Viper and an Imperial Tradesman Dual Edge, both short-bladed knives. Banihammad buys a Stanley two-piece snap knife set, and Alghamdi buys a Leatherman Wave multi-tool. All purchases are made in the same city, though the 9/11 Commission does not say where this is. [9/11 Commission, 8/26/2004, pp. 17]
bullet On August 27, Flight 77 hijacker Nawaf Alhazmi buys Leatherman multi-tool knives. [9/11 Commission, 8/26/2004, pp. 27] Although it is unknown whether any of these knives and tools are used on 9/11, the 9/11 Commission will point out, “While FAA rules did not expressly prohibit knives with blades under four inches long, the airlines’ checkpoint operations guide (which was developed in cooperation with the FAA), explicitly permitted them.” [9/11 Commission, 7/24/2004, pp. 84] Regarding Flight 93, personal financial records do not reflect weapons being purchased by any of the hijackers. However, the FBI will reportedly recover “14 knives or portions of knives, including a box cutter,” at the crash site. [9/11 Commission, 7/24/2004, pp. 457; 9/11 Commission, 8/26/2004, pp. 35]
