Square ground chain - File

[46&2]

I ignored it as i reckon he'd get a lesson in what real square is, unless as a lot do, they file it round after buying a roll of square.

I did have the one of the young blokes in our local bushfire brigade try to tell me one of the chains with the 064 on the tanker was "square chain" as it had full chisel cutters, or in his words "had square corners". :hmm3grin2orange:

Nice.

If your trying to learn to square file, I think the goofy file is easiest because the top edge lines up just right in the corner.
