Currently using a great Everlast combo blade. Got it sharpened and wow it’s amazing.

I now have a Sawstop and want to have a backup in case of a brake fire.

I have a full kerf 24t Freud glue lime rip for 3/4-2 1/4 wood. It’s ok. I noticed the left side of each tooth is chipped a little and I’ve used it once. I’m calling Freud on it.

Also have a diablo Home Depot thin kerf combo that’s for plywood and garbage like that.

I wanna get a skarpaz sf1040a. It’s a 40 tooth 20 degree atb that’s similar to a WWII by Forrest. Is the 20 degree atb grind tough to keep sharp?

I’m cutting maple and walnut and some hard apitong.

The skarpaz is only $60 new and

Assuming you’re talking about the top bevel and not the hook angle, the steeper the top bevel, the less tear out on cross grain cuts, but at the expense of decreasing edge life. Many Hi-ATB grinds feature a 40° top bevel….some closer to 30°, so a 20° top bevel should be closer to midrange. The top bevel is only one of several variables that effects edge life though. A 20° hook angle is pretty standard for most 40T general purpose blades.

How would you compare the Everlast to the Forrest WWII? A 20° atb will give a clean “glue ready” cut, but will dull quickly, especially on hard woods.

I go for the Freud Lu86 general purpose 40 tooth blade. I use it on Sawstop PCS and it works great for finished rips and crosscuts.

At sub-forty bucks, I’m not sure you could do better on the value equation.
