I’m in the process of designing a workbench.  In the past I worked on a bench improvised out of plywood without dedicated vises.  As I have gradually migrated towards using handtools — now almost exclusively — it has become painfully obvious that I need a bench with vises to hold down boards for planing, sawing, and carving. 

Here’s my question.  What vises are best suited to a handtool worker?  I realize that the answer depends on what I build (chairs vs large case pieces).  My goal, however, is to build a good all-purpose bench that will be used to build all kinds of furniture with hand tools.  Under that scenario, how would you outfit a bench?
