Trusted knife designer Ernest Emerson learned “hard work [is] the secret ingredient to success,” a belief Kershaw Knives shares. Consequently, the two collaborated and produced E-Train, a folding trainer created to introduce safely the multi-function capabilities of the wave shaped opening feature that causes knives to spring alive with released blades. Military, rescue and law enforcement personnel who seek readiness and ease of use during emergencies insist on knives with wave shaped opening feature. However, only through repeated practice do users develop the confident intensity and skill required to operate such knives. E-Train, made for the hard work of practice drills, comes with bright blue G-10 front handle for easy identification and unsharpened 3Cr13 stainless steel blade for safe handling during reps and sets. Although highly affordable, E-Train’s value is unsurpassed according to outdoor adventurers, survivalists and all others wanting to increase their knife proficiency.
