Just a warning: my Kekokrak collapsed after 4 or 5 dissections! 

The piece holding the klicky's head cracked on both sides:


Now the head can move over the critical point and thus the klicky escapes decapitation, even when the nut is maximally fastened:


The head-holding part clearly is too weak and should have been manufactured out of metal. 

Not happy with my purchase after all.
