First, this is not a true ESEE knife. The only thing about it that makes it an ESEE is the fact that the ESEE name is on it. Jeff and Mike (owners of ESEE) gave permission to a knife distributor to make this knife. It is not being manufactured by Rowen which is the company that makes all of the ESEE fixed blade models that we are familiar with. It is being manufactured by the same company (Taiwan) that manufactures the Ontario RAT 1 folders for Ontario. It doesn't carry the "no questions asked" life time warranty that the real ESEE fixed blade models have.
