I saw now for many years a great deal with my scroll saw. And for years I'm not happy that the back uproots strong and must be much ground. On the advice of a friend back I have now bought this saw blades. Actually, I had not really expected a big difference to my otherwise used saw blades. Had rather feared that on the top are also outliers now. But to my great joy, there is really virtually no fraying on the back. The edges are totally clean, I go only briefly with sandpaper over it and is good. I still have my first cut saw blade in the saw and quite a bit. Multiple superimposed 10 and 8 and 18 mm plywood glued. The saw blades keep even from some. So highly recommended!
