I had mentioned it at the recent Woodshop Basics class but I didn’t have the specs on it but the instructors said most thin blades weren’t allowed. This one is made specifically for larger shops and specifically mentions not needing stiffeners.
It’s a 6" blade, .06" thick but for the final 1/4" which is .023"
It’s used with a sled jig to cut frets for instruments. You can take forever to do it by hand but this blade makes it take only minutes
Here’s a link to the manufacturer’s website
and here’s a video of them using it on a similar large shop table saw
