Fionntan from Ulster in Northern Ireland, found the sword after trying out a metal detector he’d been given for his 10th birthday.
Some antique experts, who’ve looked at pictures of it, think the sword could be around 300-years-old dating back to the 18th Century (1700-1799).
Fionntan found the sword on his first trip out using the metal detector, and he said he felt: “quite excited” about the discovery.
