knucks

He didn't have no knucks, boys—that hard-hoofed granger just naturally tore into the Dutchman with his bare hands.

They carried slings and knucks and used to go around with grown men, sometimes Joe Pink.

However, he was willing to lend his revolver to the Marshal and a pair of brass "knucks" to Harry Squires.

And as for the pummeling I got afterward with the knucks—that was my own lookout—the railroad company is not to blame for that.
