A coworker showed me a shop made block the other day. He copied it from another coworker who said "All Chicago toolmakers have one".
The block was heat treated and ground all over. It was 2.375" x 2.125" x 3.000" long. The four corners were cut out so you have a 1/4" x 3/4" notch, a 3/4" x 5/8", 3/8" x 1/4" and 1/2" x 3/8" notch. The remaining outside surfaces have a series of 1/4-20 threaded holes for a clamp block. The ends were also drilled and tapped, and there was a 1/2" clearance hole through the whole block.
Seems like a handy little aid, able to hold many size bars, giving clear access to at least two sides of the workpiece.
Just thought I would share some metalworking content to get the average back up to where it needs to be.
