Jagged

This was a conversation early this morning just after breakfast:
Me: Where’s the rusty old saw that used to be in the Summer house?
Igor: By rusty old saw do you mean my Dad’s antique log saw that’s even older than me?
Apparently this rusty old saw antique log saw is a one man/two man lumber saw made by Taylor Brothers of Sheffield just before the First World War. His Dad used to cut logs with it when he was a lad. I think its log cutting days might be over.

It makes a reasonable jagged blip, though.
