I have two 8" saw blades for sale, both used for cutting acrylic and other plastics. One is a 60 tooth Lafayette Luxite with a kerf of about .08". The second is a 72 tooth blade with a .065 kerf and is stiffened as shown in the photo. Both were sharpened and have not been used since. They do have a 20mm bore (I had a European saw back then) but use all of my blades from that era with a 20mm -5/8" bushing with no problem. Knock them in and forget about them permanently. I recently got a Sawstop which can only use 10" blades. $30 each.
