1 Samuel 13:19-22

19 aNow there was no blacksmith to be found throughout all the land of Israel, for the Philistines said, “Lest the Hebrews make themselves swords or spears.” 20But every one of the Israelites went down to the Philistines to sharpen his plowshare, his mattock, his axe, or his sickle,
Septuagint; Hebrew plowshare
21and the charge was two-thirds of a shekel
Hebrew  was a pim
for the plowshares and for the mattocks, and a third of a shekel
A  shekel was about 2/5 ounce or 11 grams
for sharpening the axes and for setting the goads.
The meaning of the Hebrew verse is uncertain
22So on the day of the battle fthere was neither sword nor spear found in the hand of any of the people with Saul and Jonathan, but Saul and Jonathan his son had them.
