This is a GLOBAL SAW (Motoyuki) aluminum saw blade, model GA-305. It has an outer diameter of 305mm, a thickness of 2.8mm, 100 teeth, and a bore of 25.4mm. It's unclear if it was used, but there is almost no wear on the blade, and it looks close to new. However, there is rust and dirt on the surface due to long-term storage. I don't see any chipped teeth to the untrained eye, but there is a possibility I missed something. The box is dirty and shows signs of age, but I will include it as is. Please purchase only if you understand that this is a current condition item. It will be sent after a simple cleaning.
