This does bring up an interesting question. For me at least. I cut most everything on one or the other of my Excalibur saws. I usually use a #5 mgt blade but when I was trying to cut the tiny reindeer earrings that Charley makes, I tried using some Pegas 2/0 blades. Leaving everything set the same way on my saw, I would insert the blade, take the slack out of the mechanism and flip the lever on my Pegas clamps. Either the blade would break instantly or soon after I started cutting. There is no tension adjustment on these saws if you try to maintain the upper arm at level to the table. The only way I could get them to not break was to either not take the slack out, or turn the large knob at the rear a half turn. Or something like that. How do you other Pegas/Excalibur/Seyco users do it?
