If you are here asking: "Is this a science meme?"
Probably, yes. We use the Dawkins definition of meme: a replicating idea, not just an image macro with a fact on it. A good post here doesn't need to teach you something. It needs to make you ask something: who, what, where, when, and especially why or how.
Science isn't a filing cabinet of facts, it's a conversation. For example, a photo of an eel or other localized wildlife counts because most people never see one, and wonder is the first step of inquiry. A car meme counts if it makes you curious about what's under the bonnet. If you want to talk about something you noticed in the world, chances are someone else wants to talk about it too.
We moderate for vibe, not category. Pruning is light, especially where a post creates interesting discussion. Experimenting is encouraged.
See the pinned paper on Shitposting as Public Pedagogy if you want the academic case for why this works.

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.
