Re: OK I'VE BEEN CALLING THESE KNIVES . . . . . . .
Looks like they are blades/knives, unsure about the larger piece though, can't see enough. The first one & top are spearpoints, which spearpoints were utilised as blades/knives. If you see a spearpoint with one side rounded & the other notched or looking different to the rounded (blade) side. Then you can class it as a blade/knife, although we do like to try & speculate what the type is by the original side (notched). It will come with experience. I'm still learning after 3 yrs. Its ok to say most spearpoints are blades though, until you get more experience to type them.
If you say what state they are from someone might tell you what that top & first spearpoints are..
Hope this helps, takes time to type.
