We are offering up this very, very rare Mark I knife the Gerber Mark I Tactical, #5610. Serial #K6493S – Rarely seen these were made by Gerber from 1988-1994 but very few quantities were ever made or released to the market. I was told by a retired Gerber employee these double serrated knives were made for the commercial fishing industry as a “last ditch” tool should a person become entangled in a net. You can search Ebay to see the number of these that get listed, very few if any have I seen for sale over the past few years. This Mark I is NIB, has never been carried, sharpened and is in “Dead Mint” condition. Box shows some storage wear but is proper to the knife as is the sheath. If you are looking for a true collector oddity than this may fit the bill as I doubt you will find a more sought after Mark I. NIB Mark I’s on Ebay are currently selling in excess of $275.00 and they are much more common that the Mark I Tactical Knife.
