For all who are still looking for blades for this unit......go to Sears. I just purchased 3 sets from my local store. They are marketed under p/n 922993 4 1/8 jointer blades. These are a perfect match to the ones in my machine...same length, thickness, width and hole pattern. And they work perfectly.Apparently made for Sear latest model.
Strange when calling Sears parts, they don't know that this item will fit the older jointers.
