1 Samuel 13:20-21

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
