This is the 111m Dutch Army Knife, the standard issue of the Dutch armed forces (army, air force and navy). This is the 1993 model, which was replaced by the new (and current) model in 2010.
The scales are green (olive drab) nylon, with the so called “interservice” logo of the Dutch armed forces.
The interservice logo represents three branches of the Dutch armed forces: the army, navy and air force.
For some reason, “T56” is stamped on the back scale. I haven’t yet figured out what it means. I have seen someone with a different number stamped on the back scale, he suggested it may have been a (numbered) test run of these knives before it as decided to issue these to the troops.
