I haven’t bought standard Anco in a while. I had a bunch of the standard ones but lost them over the years even though I prefer using those refill inserts if I can find them. I bought a bunch from RockAuto a few years ago.
So I got a pair of traditional Anco blades, only to find out the label says Trico Products and part of the Fram Group. And it doesn’t look easy to replace the insert, which used to be a plastic rail frame. I used to just pop out the insert and the standard width replacement could be squeezed in, although I usually pull out the clip. Not sure how hard it would be to pull out the metal rib inserts on these (at least they’re not crimped in place), but it might be possible to use my plastic rail refills although I might need to keep the metal clip to keep them from sliding out.
