I picked up a set of Starrett No. 243 Hermaphrodite Fixed Joint calipers on E-Bay the other day. They work great for scribing a border around the edge of a workpiece. They are a one-trick pony (that's all they do) but they do a good job at it. The fixed (friction) joint is not as stout as the threaded adjustment on a spring caliper but if you are careful they stay put. I haven't seen this style discussed here.
