Steelforce is still around. IIRC, Schwacker bought them. If not them, one of the other mechanicals outfits. I've got a 3-pack of 300gr left bevels that I bought for my fairy dust experiments, but I wound up with a hand injury and crossbow so they're going on bolts instead. Seem stout enough, if not quite as stout as a Tuffhead or Grizzly or Cutthroat. Can't recall offhand if I got them from 3Rivers or Lancaster, but they're on the market if you want a 3-pack of whatever.
