My Windsor chair’s seat surface shows tool marks… the rain gutter is hand-carved with a chisel and mallet.
The peg of the leg is prominent. This is an intentional effect as similar 18th century chairs would appear today. The reason I do this is to make the chairs compatible with other period pieces and have the character to fit in with your collection of antiques.
It would be easier just to sand it smooth, but then it wouldn’t have the character to fit in with your period pieces.
