Great, Cornelis, thank you!  
 
Here we have are another superb example of 16th c. combination tools: 
the one on top acted as a scourer for the barrel of an arquebus (which of course makes this the 
Katzbalger of a 
Doppelsöldner!), one is combined with a screwdriver, another is threaded for acting as a corkscrew .. 
Best,
Michael
