Well what's the evidence that these ancient egyptian branding irons were intended for use on cattle in the first place? Genuinely curious here if anyone knows the answer!

(After all, comparing the evidence we have for their different possible uses would be the best way to evaluate the strength of this argument. For instance, if we had extant cow hides bearing brand-marks that matched the patterns on some of the irons, or visual depictions of branded cattle, or textual descriptions of people branding cattle using branding irons, that would be pretty strong evidence for that form of use.)
