This is an authentic ancient Canaanite copper saw blade! This particular specimen dates back to the Early Bronze Age (ca. 3000 - 2100 BCE). 

Ancient blades of this style and manufacture are often misattributed (knowingly or otherwise) to the Luristan culture but, upon expert consultation, we have found it to be Canaanite. 

This ancient artifact measures ~10.5" long and worldwide shipping is available!
