It's certainly attainable JD if we want it. Bars can be hardened to cut piano wire like cheese should one desire it. And that without as much as marking the bar. Ron N replied: >Not necessarily.

However, to follow on from Johns comments, I suspect that smaller radius bars produces less distortion. The 55 gallon drum is an interesting analogy to the larger radius bar. The large radius bar will actually cause the effective string length to shorten and lengthen as the string goes through each cycle. I haven't proven this by experiment, but it sure seems to have legs, if the bars (either duplex or capo) have a large radius, the tone doesn't seem to be any good. It changes radically for the better when the bar radii are reduced.
