What do you call these?

[Aurora1959]

Distinctly teardrop shaped with one end pointed. Ritchie calls them "strike-a-lights". Some people theorize they might have been knapping tools. Pretty common in Central New York.

No. Not strike-a-lights (Terminal Archaic, as I recall). If so, at least one edge of each would be battered and blunted by being struck with iron pyrites to produce sparks. The few I'm familiar with had Susuehanna Broadpoint-type notches, were of chert and/or South Mountain metarhyolite) and were hafted like scrapers made on points were in Early Woodland (referencing east central Pennsylvania) (West Bank Backwater Archaic sites).

FWIW

They look like the correct size/shape, but Overstreet says, "The striking edge usually shows extreme wear."
