Pieces of leather that are stitched and/or tacked around an oar to protect it where it rides in the oar lock. They usually have a stop or "button" to keep the oar from sliding out of the oar lock when left unattended. The button can be a thin strip of leather or knotted twine that is tacked and/or glued in place on top of the leather at the handle end of the oar.
