Nick and Simon at the G7th Capo Company have done it again. I think this 'Heritage' model is the tops and it has my full endorsement!!!!! Take a look at the video to see why, then click on this link to read more about it: http://www.g7th.com/heritage-capos.aspx
The most amazing feature with this capo is the patented Adjustable Radius Technology - A.R.T. which allows the capo to fit to virtually ANY fretboard radius, making it an outstanding versatile tool!! Here's Nick Campling at G7th Capo Company explaining this feature. That explanation starts at approximately 2:32 minutes into the video.
