Yes to the MK blades. And I will never again buy what are sold as MK look alike, compatible or others pretending to be an MK Diamond Blade. I purchased what I was told was an MK 18 inch Diamond blade last year, but it was a knock-off, not a true MK blade. The metal was soft, it had a warp in it and it has never cut correctly. The company I purchased it from said that due to COVID, all the blades and metal items produced overseas are now second rate. He even said MK has the same problem. Anyway, I kept the blade and used it and have nothing but regrets. They offered to replace the blade but what good is that, plus pay for more shipping!!!! Anyway, if it does not say it is manufactured by MK, and does not have the MK logo on it, you might want to reconsider, if you are truly looking for an MK blade.
Yes, there are other good quality blades out there.
I also believe in using a stick to refinish the blade as it wears. I use a 1 inch square piece and make several passes and the blade cuts much better.
good times and good luck
