Does anybody know what this tool is called? Productive work has crawled to a stop while we try and figure out what the red thing on the cover of Microsoft SQL Server 2012 Internals (2013, 0735658560) is. We think it's a surgical or electrical tool of some sort? 



Thoughts?
It's a pair of canvas pliers. They're used to stretch canvas over braces, used in painting prep.
