Richard - I've read your post with interest; sorry I don't have any 
knowldege about the square you described.  But, I do have a question 
for you:  About thirty years ago I purchased some Swedish-made wood 
chisels when I lived in Brazil.  They are still with me, and have 
proven to be the best tools I've ever had.  Is the manufacturer still 
in business and do they have a US distributer?  The name on the chisel 
is  and on the larger sizes there 
is a fish -- possibly a dolphin or a whale.  If you don't know about 
the US distributer, I would be happy for their Swedish address so I 
can write/telephone/e-mail.   Many thanks in advance.  Dave Anderson
