The Strider MB Karambit is a very limited production combat tool. 

Recently Strider did a special modified run of MB's for a unit that shall remain anonymous and we were fortunate enough to secure several that were extras left over from that batch.  These MB's feature the massive blade profile that operators are accustomed to along with two different grooved thumb ramps designed for different grip angles when holding the knife.  The MB is ideal as a "vest knife" for your tactical vest or as an every-day-carry tool for large framed individuals.  This lot also has deep grooved dark green G10 handles for maximum purchase with or without a gloved hand.  Supplied with a Kydex sheath and Tek-Loc.

People have been waiting for another run of the MB for several years and it will no doubt be a long time until more are made.  Get one while you can.
