RE: Wasp Jackhammer 1 1/4" cut test results
Replacement blades and mechanicals go hand in hand. Most are a pain to replace, what with those small set screws etc. Some of the sharpest are Rocky and NAP mechanicals, and some of the strongest blades are on the Vortex line of heads. Right off the top of my head though I can't think of any that are "easy" though.
