While you allready on it. Could you maybe get impact driver and try it too ?I just tested 10 coke machine with the orange ratchet and 10 with the blue wrench, it's essentially the same. I got one more steel bar with the wrench and a few more mechanical parts with the ratchet. This is not enough variation to signal a difference. Perhaps I need a larger sample size, say 100, but I'm not interested in doing that.
I am harvesting more stuff than earlier probably because of my game stage. Perks haven't changed, I put one point into salvage operation shortly after I looted my first wrench.

But i don't think it would change anything at the result.
The tool just made it faster to salvage the object but don't give more out. Only perks/traits affect it.
