Spear and Jackson dove tail saw

Continuing with old hand tools and the excellence of their manufacture,Notty has found a small 'Old Ladies' hand saw in his late mothers tool box,its interesting to note it had a composite construction and while brass was not used for the blades back strip,a special none magnetic metal was.

Hi Roy,

After seeing that fine list of ancient British saws, I couldn't resist going to get the saw and looking to see if there was any lettering on it and there was!
It's a Spear & Jackson Leap-Frog made in Sheffield: Warrented Cast Steel; but there is no date on it.
The blade is 10-inches long by 2-inches wide at the handle end (not counting the back stiffener) and 1.5-inches at the taper end and its quite heavy but less than 2-kg I'm sure. I checked the blade with a magnet and it is steel but the stiffener is non ferrous because it is not magnetic but looks like gunmetal? Amazing what you come across hey?

Notty.
