I know it's been almost a decade since this post, but I recently came across this tape measure in a Peter Millard video and then found it in a couple other videos.
I'm intrigued by it, but have some questions. Everyone describes using this as a measurement transfer device, not an actual measuring device. So, the first question is what are the profiles of the marking pins like? Are they sharp knife-edge like a true marking knife? The only in-use video I saw was from a drywaller (http://www.youtube.com/watch?v=e4gpLD5SE6w ),
where he took an inside measurement, then moved to his drywall panel and scribed a mark. OK, well, drywall's not an exact thing. How would this work for measuring an inside cleat where you wanted a perfect fit side to side?
How do you even read the thing? Here's a shot from another video (http://www.youtube.com/watch?v=nQkP_Lhe2hA ):

Where's the witness mark? Is it the edge of the plastic case, or the edge of the metal guides, or something else? And since the tip doesn't move is that only for inside measurements or only for outside measurements?
Speaking of the tip, here's a shot:

That doesn't look great to me, but it seems that the tip is set for an outside measurement.
So, what's all the buzz about this metric tape measure? I'm not seeing it.
