Mystery Wax Seal Blacksmith Latin Device, Turned Boxwood, Late 17th Century

Beautiful thumb seal, flat and round, with a dorsale, inlaid and riveted in a superb and powerful boxwood turning, as was done in 16th century and 17th, early period.
The large seal, (30 mm) is deeply engraved of a Latin motto: NEMINI CUDO N ALUM: "I do not forge misfortune for anyone" or "I do not forge evil for anyone." What is interesting is the use of cudo, which refers to the action of striking, of producing by striking, forging. The meaning in medieval Latin is "to forge." Perhaps the strange signs are forging instruments, an anvil?"
Thanks to Marie, who was kind enough to enlighten me on this point.
As a coat of arms, a strange sign, an X-pattée figure, comprising 2 stars, is crowned by a helmet or mask, two scrolls held by a standing female figure.
As beautiful as it is interesting.
