you gutys ever look into the stellite blades- they are set up like a carbide with the tips welded on, except these are about 1/2 the price- and are easily resharpenable, as its not carbide- so dont need a diamond wheel.- with 10 to 14 resharpens per blade!
we use them on our big resaws- and they really cut well- not as nicely as a carbide- but way nicer than a set tooth blade.
