All my Pegas "Skip" and "doubled skip" blades I have, have that Configuration at the top of the blades,,, without the notch lower down... I like it because it tells me easily which way is up and I don't have to grind a point at the top,,,, I do that on all my blades,,, helps when bottom feeding... I just got the "double skip" last month,,,, the "skip" ones I received a couple months ago..
