What Book of Mormon hero killed six Lamanites with a sling, cut off the arms of many more, and then carried the arms back to show the king?


Ammon

Ammon stood forth and began to cast stones at them with his sling; yea, with mighty power he did sling stones amongst them; and thus he slew a certain number of them. ...

But behold, every man that lifted his club to smite Ammon, he smote off their arms with his sword. ...

Now six of them had fallen by the sling ... and he smote off as many of their arms as were lifted against him, and they were not a few.

He ... then went in unto the king, bearing the arms which had been smitten off. Alma 17:36-39
