Review title: Review of Delta 22-562 12-inch Steel Planer Knives
Product review: After using the original blades for quite a while, they had become quite jagged from hitting buried nails in the wood I was planing. So I was really thrilled with the results from these replacement blades. These blades provide a very smooth surface, just like when the planer was new. I was also very pleased with the ease of replacement--it went quick and was easy to set up the alignment. I recommend having replacement blades for all planer users. And Amazon had the lowest price for these blades.
