just fine. I find them at least as sharp, if not a little sharper. While I'd probably prefer the ones made specifically for the Olfa cutter, the price difference makes the Harbor Freight ones definitely worth it!
The biggest upside is that I don't hesitate to change blades the way I did when they were several $$ apiece!
I like them just as well as the more expensive ones. No problems at all.
Just an FYI though, the blades fit the 45 mm cutter and not the 60 mm.
