Today I was invited to visit the 3M laboratory, they showed me their workshop where demos and testing are made. 3M commonly renowned here for sandpaper and adhesives when in fact is just the tip of the iceberg. They have airtools, powertools, safety equipment, medical supplies, electronics and just about anything for anything...
And since my interest is craftsmanship tools, I took a very short clip of what is in store for us.

something that caught my interest is the surface conditioning material called "Bristle" it is best seen than described. So do expect a field trip soon to the 3M laboratory...
