Sharp
Used on a cordless 12 volt Royobi circular saw I have had for 30 years . Nice sharp thin kerf blade.

Clean cut with my C3 Saw
Made multiple very clean cuts on treated 1x6. I have a craftsmen C3 saw which felt renewed with this blade

Excellent blade at a great price
Bought this for my 18v cordless firestorm circular saw. I've already used it on 2x4s and plywood, and it cuts quickly, cleanly, and with a smaller kerf than my 7 1/2" circular saw. It is still a rough cut blade, so you may have tear off, so know that going in. I'd knocked some of the carbide bits off my old blade and while it still cut, this is a huge improvement, even from when my old blade was brand new. Highly recommend this blade.

Well worth it!
This is a fantastic blade. I use it with my M12 Milwaukee circular saw. I will for sure get another when this one wears out. I've cut a lot of 2x material as well as 3/4 ply and MDF. Highly recommend. I love Irwin paddle bits as well.

Much better than blade that came with my saw
Used to cut plywood and 2x4s so far. Clean cuts and easy handling. Better quality than factory roybi blade.
