After surviving one of the most extensive test and evaluation programs ever undertaken by the U.S. Government, including knives from most U.S. cutlery manufacturers, the SOG SEAL Knife triumphed. The SEALs are one of the most specialized elite military groups in the world today. SEALs must undergo one of the most rigorous training programs devised to produce the consummate warrior. Only a select few endure and earn the right to wear the SEAL Trident on their uniform. The SEAL knife evaluation program included: tip breaking stress, blade breaking limit, sharpness, edge retention, handle twist off force, two week salt water immersion tests, gasoline and acetylene torch resistance, chopping, hammering, prying, penetration tests, cutting six different types of rope and line, plus an intense hands-on competition in the field.
