I use two types of blades mostly - Flying Dutchman and Pegas. Also have a few from Niqua.
One thing that is irritating is that each brand cuts at a different angle. That is, to cut a straight line, you have to angle your wood differently with each brand, and sometimes with each type of blade.
With one brand, you have to angle to cut line towards 1 o'clock or 2 o'clock. With a different brand, you have to angle the cut line towards 10 o'clock or 11 o'clock.
I guess if you use only one brand all the time, you will become so used to it that it won't be an issue. However, I have too many blades of each brand to just throw them out. Since the blades seem to last a long time, and do not break, it will take some time to use up.
No real point here, just venting.
