I have ordered some FD blades. The last I got of Olson's just didn't cut right, The new blades cut like they were dull I know they were new I just opened a new batch of 12 and they were the same, so i decided to got to FD. I am talking about flat blades Just to let you know it's not just F D blades, I figured that Olson got some bad steel. I didn't buy these blades from The Wooden teddy bear I bought them from Wood crafts. store.
