Minty double edged nickel plated blade with the German maker's name and trademark: CARL EICKHORN-SOLINGEN and a sitting squirrel on the ricasso. White felt washer intact.

A very nice Dutch Royal Air Force dirk. This particular example still has 100 % of the gilt intact.

This dirk is a unique design of the Dutch military artist:  J. F. H. Th. (Frans) Smits, and produced in a very limited number only in 1961. 
Mr. J. F. H. Th. Smits ( 1915 - 2006) was also the designer of the Dutch M 1955 Royal Dutch Air Force officers sword, the M 1966 State Police Chief officers sword and the M 1961 Municipal police  chief officers sword.
