Ralph Jackson comments:

Bronze was rarely used for Roman scalpel blades, which were almost invariably of iron and, as a single, un-associated, un-contexted object of idiosyncratic form caution is necessary. However given a) the shape of the Caston blade and the form of its cutting edge and b) the fact that Britain has yielded a number of variant forms of Roman medical and surgical tools, I think it is reasonable to describe it as a possible Roman-period scalpel.
