Combination wrench with Stop Ring

What do the symbols mean?

Combination wrench with new Stop Ring function and extra closely spaced 72-tooth mechanism that only requires 5 degrees of movement. 




Heavy-duty mechanism with reversal, which can be changed without removing the key from the bolt or nut. Made of chrome vanadium steel with a chrome-plated Silk finish. 12-edge OPTIPUNKT shape in the ring part. 




The Stop Ring function means that the head of the nut/bolt is locked in the key, which means that the key cannot be moved past the head. The stop ring make it easier when loosening nuts in hard-to-reach places as the nut remains in the wrench after it has released from the threads, instead of falling out and being lost.
