The SAR is all muscle and specially built for SERE/E (Survival, Evasion, Resistance, Extraction/Escaping). The custom recurve blade style in a 'S-type' shape creates an exaggerated forward belly that helps the operator easily slice and chop their way out of a situation. The grooved section on the SAR’s spine gives a better non-slip surface when applying pressure to the blade with the thumb. The SAR is made with our special blend of titanium, which has very superior wear resistance and is “thru-hardened” to Rockwell C 47, while still maintaining its flexibility. This knife will never rust or corrode. All SARs are first run knives with serialized tangs making them highly collectable.
