I'm building a retaining wall flowerbed and using a chop saw with 14" wet/dry diamond blade. I have been dry cutting the blocks and it cuts them great. Well, now I think the blade is starting to get dull. I am working on the cap now, and at the end of the cut the blade is chipping the corner of the cap. It doesn't matter if I go fast or slow. It still chips the last 1/4". The blade still cuts well, but this chipping just started. Is there a way to sharpen this blade? There is still a lot of depth left on the teeth. I don't have too many cuts left, but I would like it to look nice and not chip the rest of the caps. Thanks for any help!
