The point in the photo has definitely been resharpened [new flakes driven off the edge], but that’s not unusual on a hafted tool. Making a blade dos not take near as much time as hafting it so there is a lot of incentive to “use up” a hafted tool until there’s not enough left to sharpen; in the course of such usage the function of the tool may change; an old blade may be better suited to prying open mussels or skinning than a new one, or even burnishing. The ideal tool for cutting, say hides, isn’t a well worked blade but simply a flake knocked off of a chert or obsidian core, esp. one with a hook to it.
