Bitch Pick

[Simon Brown <moonsong@zzzzzzzzzzzzzzz>]

I recently bought a book 'Medieval Building Techniques (by Gunther Binding):
 http://www.buildersbooksource.com/cgi-bin/booksite/20777.html

There are over 700 drawings of Medieval building workers in action. I was
astounded by the number of drawings featuring stoneworkers wielding a
pointed pick or stone hammer, compared to those using mallet and chisel.

Now, I know that it is likely that the illustrators were not likely to be
stone carvers, but the consistency across several centuries and many countries
is beyond coincidence.

In the foreword, Dr Glynn Coppack (Author of 'Fountains Abbey:
http://cistercians.shef.ac.uk/fountains/precinct/index-notes.php)
describes stone as being worked generally with axe and hammer, on the ground -
mallet & chisel not being used until the fourteenth century.

Well, my question is - what do you call a stone hammer when it's not a bush
hammer (a "Bouchard")?

The closest I can find locally is called a 'bitch pick' with 'pups & claw
holder sold separately'. That is, a double-ended stone working pick (bitch)
with replaceable tips (pups), one a sharp point, and the other a scutch or claw.

I've had no success Googling 'Bitch Pick'. Any clues?
