The "Guide" is not in English or German, probably Chinese. But there are English "instructions" in the net.
What I do not like the article:
- The "knife" is dull and can not be sharpened.
- The "screwdriver" is too thick, you can fit into a slot barely clean.
- The 6-kant wrenches are unsuitable.
What I could have really used well are bottle opener, can opener and ruler.
Mediocre or pretty useless are Saw (too short) or protractor (for what?)
So all in all a "nice toy", nothing more.
