blocks
I had tufinol? blocks on my previous boat which was a 1967 Alberg designed Corinthian Sailstar. Loved them. They always worked, edges of the sheaves and cheeks did not ever break. When they fade in color you can just put some WD 40 on them and they soaked it up and got their dark plum color again. I liked the traditional look. I sold the boat two years ago and all of the original hardware was still on the boat in working order and still is to this day. Not many things last for 45 years these days but those blocks and sheaves did!
