<p>At roughly the timestamp above the architect uses an odd looking metal straightedge and I was wondering what it was called. I thought it was a regular architect's scale at first, but two of the fins are small. I can't make out any brand marks and have so far had no luck finding out what it is. </p>

<p>Have any of you seen something similar?</p>

The only thing that seems to match your description is the "ruler/triangle" segment at time 8:50.  Is that what you're referring to?  I haven't seen one like the one shown there.
