I just had to stop and give a tip of the hat to Tom Waltz and Carbide Processors. The cuts with their 55T plywood blade (37322) are nothing short of outstanding. The total absence of saw marks on this none-too-flat shop ply is amazing. A good saw setup is critical but, quality cutters really take advantage of a tuned up saw.
The carbide on their blades is massive. I have a couple of blades that have been sharpened once and would not be able to tell you which they were if I didn't know. The usable lifetime of these cutters is top notch and this makes them a great value.
OK, I'm off my soap box
