Kinda like the little nib on top of old saw blades. It doesn't really do anything, but if they can make that complex little nib, then they can probably make pretty decent sawblades too.
I've always heard that the nib was meant to help you gauge when to stop your pull stroke and start your push stroke so that you use the whole saw and don't wear the teeth unevenly. Is this not the case?
Nib only exists to prove your saw maker was a competent professional
Google says it's a vestigial ornament to represent a handle from when steel quality was poor.
That is all saws used to have two handles because of poor steel quality. The nib was where the front handle would attach. Later the front handle wasn't needed but the nib remained and was later shrunk.
A toolmaker could put a nib and still have bad quality teeth. Doesn't seem like you would judge quality by the nib.
