Both archaic for sure, the first one is a knife, and so is the second one. The first one looks like it's made of Cobden flint, and the second from Burlington. I would call the second one an archaic side notch. Hemphill is the name I lean towards. I have one similar, and I'll see if I can find a pic. of it for you to see. The notches don't really fit into the St. Charles/Dovetail type.

P.S. This is the only pic. I have on this computer, but hope this helps.
