I missed this thread a few weeks ago...Probably didn't enter because normally I'm not a big Mac Tools fan (unless it is old stuff)
Well...met up with a guy I was buying some Snap-On stuff from and he had a bunch of tools for sale from a tool box that he bought complete with tools.
He had a set of these for sale and they caught my eye. Having never heard of them, I checked them out and they seemed like top quality...Perfect chrome, nice length, VERY nice beam thickness, really impressed me actually. So I bought them...but I missed the metric set he had for sale!
Since I hadn't ever heard of them, I searched on here and hit this recent thread.
I thought I would add some pics for your viewing.
Here is a shot of the beam thickness on the 5/8" in relation to a Cornwell X-Long 5/8" combo. The MAC is thicker...(Cornwell is at the top of the photo)
