Got a Hazet v-10 wrench today and some one told me it is from a Porsche. Can anyone tell me more about this wrench. It has 8 and 13mm ends. I did another search and found they are in a lot of German cars?
A couple of my VW Beetles came with Hazet 8x10mm wrenches. Some VWs came with Hazet 10X13mm wrenches also. Most BMW come with Heyco wrenches.

Those old car tool kit wrenches are like the infamous Ikea Hex keys. Everyone over here has one lying around somewhere.Millions of these were supplied as standard tools in German cars

The 10x13mm wrench was much more useful.sorry, nothing special...
Millions of these were supplied as standard tools in German cars,
but their quality was only mediocre for their intended purpose.
They are nothing like the wrenches used in professional workshops.
Some of my VW Bay window T2 bus 1967-1979 size 10x13 -
have also smaller ones as yours without photos for my VW Karmann-Ghia 1955-1974
