Great blades for any beginner builder for even an experienced one just wanting a nice blade. They slide right on the shaft with just a bead between the body and the blade. No need for a clevis and they work great.
bought these nice blades a few weeks ago to make my own PM like spinners, the blades rotates at any speed which other blades don't. i took some to a friends pond. and catched dozens of panfish,trout,bass and even catfish. so if you wanna make your own PM spinners at a fraction of the price, give these a try you won't be disappointed.
