In Canada it is aslo cutterschoice and I see they share an address with laser sales, also have an Eirie PA. address. The Laser is rebadged Windsor chain if I am not mistaken. I ordered some from cutters choice as in semi chisel as I find it bore cuts slightly better than Carlton which I usually get from Baileys. They shipped my Carleton anyways so they probably carry that line too. Both Carlton and Windsor as well as Oregon are now part of one big company.
The Laser chain used to be available in both low kickback and regular professional configurations in chisel and semi chisel. I never had any problems with quality. Zip Pen I think was the original company and they decided they needed a more modern name a few years back and spawned the cutters choice, and pro kut names but the letterhead address is both at the same location.
