Have not had luck with no name blades. The titanium blades are expensive but last well. My beef is with proprietary blades (like Martelli) that must be used in their cutter. And the specific shape of the blades is a little different for each brand. So I now have 60mm for Fiskars, Olfa and Martelli; 45 mm for Fiskars and Olfa and 28 mm for Fiskars.
It is just like the connections for charging electronics. USB B type, USB C type, lightning connectors. I leave home for three days and have four or five charging cords. None transferable.
