Probably the first thing to agree upon is the definition of a prototype dagger .....
Anybody willing to try ?
To me the name 'prototype' is a bad choise. Prototypes from whatever objects are not realy in use in daily life. They're made as a testobject to discover positive and negative features of it and to see what could be improved.
These early Christmas daggers, SA's and SS's, were accepted and distributed to some high leaders.
Imo the naming (rare) 1st type M33 would be better choise.
Just like is the case with M36 daggers.
