How it was tested

  • mild steel tube speed test (1in x 3/32in), single pass
  • angle iron speed test (3/16in x 1.5in mild steel), 3-cut average, with decibel and airborne dust particle counts
  • 4140 hardened steel speed test (1/4in x 2in), single pass, with metal temperature rise
  • angle iron re-test after 4140 exposure, to measure speed degradation vs the original average
  • AR400 armor plate speed test (extreme hardness), single pass
  • final angle iron re-test after AR400 exposure, to measure cumulative wear/abuse resistance

If I had to choose this one blade, I would definitely go with the Makita, but it is very expensive. Also, I really like the Irwin and the Diablo.
