Stillman sizes;
on ebay, someone is selling a 2 page ad for saw sets, in the ad there is also the Stillman
saw sets.
a no. 0 for hand saws, $3.50 per dozen. weight per dozen, 3 pounds
( approx. 4 oz. each )
a no. 00 for crosscut saws. $7.00 per dozen. weight per dozen, 6 pounds
( approx. 8 oz. each )
the smaller on is 1/2 the weight.
2 sizes makes sence as the crosscut saws teeth are greater than the hand saws.
no. o has a flat at the end of the handle and the no. 00 is round at the end.
