Welcome JY. If your saw accepts both plain and pin end blades I would suggest plain over pin. Most common sizes being #3, #5, and #7 double tooth is a decent start. Popular brands being Olson and Flying Dutchman. Read your manual and search net for endless information. Other than that practice cutting woods such as plywood or any hardwood ¼", ½" or ¾" for starters. Most important wear a good quality dust mask to protect your lungs. Happy scrolling.
