I was skeptical when Norm first introduced these clamps, but he uses them a lot. Try to find them, though. I've never seen them in a catalog and only a couple of stores. And they're not cheap; even more dear than the K-bodies.
There was once an extensive thread on one of the woodworking fora about the true identity of these clamps, and it appears I may have originally misidentified them. According to the ad at the Cheyenne Sales website the nomenclature, at least with U.S. distributors, is SG-4WP. Still expensive, though.
