ESEE Knives introduced the Tertiary knife at the 2016 BLADE Show. The Tertiary was developed by SWAT officer Lee Smith as a Law Enforcement / Military defense tool. Born from the legendary Izula line, the “Tertiary” name (meaning third in order or level) comes from an edged weapon’s natural place in the panoply of personal weapons (primary firearm, backup firearm and then close-quarters weapons). Its design characteristics target specific professional needs such as swift, effective deployment, reliable cutting and penetration, low visibility profile, modular carry options, and robust construction. Simple straight punch, jab, and hammer fist strikes yield tremendous cutting potential with minimal training or effort. The sheath works well in the waist area from the 10 to 2 o’clock positions. Clipped in a vertical position under a duty belt or inside the pants gives more than enough retention for a clean draw stroke and safe re-sheathing. The clip plate can be removed to expose the accessory holes to facilitate paracording to MOLLE webbing, or worn as a neck sheath.
