#6 looks a little bit like a mining company or a forge.
so a way to early prestage of our products :-) Sorry if i am not able to tell you exactly what pictorial i like to see, (currently we use a sawblad, a part of a chain-saw, 2 mill and a machine knife in combination)
My intention was to change the "small tools" into "machinery" or "man working on machines" but im not sure if there is a way to push a pictorial in this way.
