Dwight,

The froe is definitely blacksmith made.

The adz is certainly a cooper's adz.  This is a standard for English 
coopering
and coopering traditions that derive from English practices.  The style 
appears
to have been derived from a less common French form used specifically 
for trussing
up.  Sometimes it is called a "trussing adz" in fact.  The earliest 
image I have
of this style comes from an 18th Century book, Utensiles de Tonnelerie 
XVIIIe.

Here's a photo of the trussing adz at work:

I have two other images that show trussing adzes that have no sharp edge 
at all.
