DW733 blades

Good factory replacement knives. Easy to install with no adjustment necessary. They are double sided so when one side is dull or nicked up you can flip them over. These blades are not supposed to be sharpened but replaced when used up, so you will have the ongoing cost of blade replacement, Blades work wonderful and the planer itself is a great tool. The only concern I ever have with these blades is that the two times . Additionally they are very sharp and if they worked their way out of the package could easily cut through the envelope and any hand that is touching them. The product itself though is what I am accustomed to in the DeWalt line of tools and works wonderful.
