I have been using a pro slicer 10" blade for a while now. I am finding that it started out fantastic. It cut quiet and cut well. I now feel it isn't lasting as long as the blade I was using before.
Now looking at another replacement blade, I can get a sintered rim or a notch rim for the same price. Which is going to cut better?

Pro slicer's big selling point is their thinness- I think the 10" has what- a .02" kerf or so? (I see 2 thickness' listed here:http://www.cabbingmachines.com/saw_blades.shtml, so yeah a .02 and a .04, both really thin) Stepping up to a heavier duty blade is sure to give a longer service life but at the expense of more material lost with each cut. As for cutting "better"- that kind of depends, a notch rim will probably cut a bit faster but maybe not leave the surface quite as smooth compared to a sintered rim, and my guess is that the notch rim will last longer since it should be inherently better with cooling since it has less material in contact with the cutting surface at any given instant.
On my big (18") slab saw I have two blades that I go back and forth with, a segmented one which is really thick and a notched rim which is not quite as thick, but both of them are still at 0.1" + (or so) kerf , so anything you get for a 10" should be better than that.

The Pro Slicer is a thin plated blade so not known for long life. If you have a power feed a thicker blade (.040")would be more forgiving. For hand trimming thinner is ok. Any blade will get dull and need to be dressed. Not sure how successful you would be with the plated blade unless you try a 220 or finer dressing stick as you may rip the diamonds off with a course one. Sintered blades generally cut smoother than "notched" but that is a little confusing because the no longer available MK/Barranca notched rim was sintered (diamond was cooked into the notched edge) while the Chinese crimped edge blades are not (to my knowledge). To add to the confusion the sintered MK/BD replacement blade has notched segments in the sintered rim. By the way, I just got word the Korean/Chinese import tariff finally passed so MK/BD will increase blade prices 5% (I think actual tariff was 10%-15%) on Jan 1st. Likely to see the Chinese blades increase also as it is a punitive tariff on Chinese products also.
