Some time back, soon after Pegas first hit the market, there was a problem with some Pegas blades. They broke easily. Some people returned theirs and got replacements, I did not, because I had bought some of the identified "bad" ones but I had mixed they in with all the others I had that were not part of that batch. I can tell the difference by the way they were cut at the top of the blade. Anyway, it has turned out okay for me. I am just finishing a project that I use that type/size on. I still appreciate that the blade had some flaw.. I scroll with a "Bad" one and it breaks at the same spot every time I use one of them, but it breaks at just about the time I am thinking I need to change blades because I am loosing some control of the cutting. With the ones that are not bad, I would probably be changing after close to the same amount of use. The only down side, is if you have a Hegner, you can appreciate the trauma of a blade breaking event. I have had the Hegner for quite some time, and yet I still jump and the heart pounds after a blade snaps. It is still quit stimulating! Not sure why I posted this, just thought of it because thread is about blades and well I just felt like posting it.
