I broke the blade on my coping saw and went to the appropriate container to obtain a replacement. I wonder how long ago my granda had bought these, definitely look like something from the 1960s:
ECLIPSE COPING SAW BLADES
MADE IN SHEFFIELD, ENGLAND, BY JAMES NEILL & COMPANY ( SHEFFIELD ) LTD
Still perfectly usable, no corrosion after half a century of storage! Two remaining in the box, once I've used those I suppose I could buy a contemporary pack and transfer the contents into the box. Apparently they are still made in Sheffield. I hope that doesn't just mean packaged in Sheffield...
