Found a vintage Benchmade Emerson Design assisted Knife in my late sons storage unit. He was a 20 yr combat Vet, USMC. I understand this is a pretty rare knife and was discontinued years ago. Blade is 3 3/4" long and opened is knife is a tad over 9". Push to assist in opening. In excellent condition. My son was a advid knife collector. Shipping will include full insurance. Check photos for more info. I am not a knife expert.
