Has anyone seen chain like this before? It has this 'vertical' cutter between every normal cutter; it came in an Oregon chain box but no saying if that was the original box. The pattern is left chisel cutter, 'vertical' cutter, right chisel cutter, 'vertical' cutter, repeat. I've got it on a 24" bar & with my mildly ported jonsereds 920 it seems to cut as well as any other chain.
Can't find anything online about, curious to see if anyone knows what it might be for?
