correct hammer shaping

lately I've been averaging about 2 actions per week; most are filing & 
reshaping jobs. Most have hammers that are being filed for the first time. 
The last grand action I brought to my shop for this treatment had hammers 
that were previously filed (maybe 10 or more years ago) but were reshaped 
quite poorly, either as a result of haste, lack of skill or both. Not only 
was the felt TOTALLY asymetrical, but the strike points were so off-angle 
that only ONE, maybe two strings (of a three string unison) were being 
struck, even with a moderate blow! The angled hammers were the worst because 
whoever filed them last time seemed to be filing ALL the hammers in the SAME 
up & back direction as the keys, instead of in the natural direction 
dictated by each individual hammer. I've seen this odd and incorrect filing 
method a couple of times before, and have wondered if the same person was 
responsible.
