....The only caution would be that the shock wave propagates through the blade at 20,000 ft/sec, reaching the center in 3 nano-seconds. This may cause the blade to explode in a sort of sonic boom if the two waves collide in the center out of phase. In phase they would just cancel each other out quietly....
This is cause for great concern to me. If I accidentally grind a knife and create a standing wave consisting of the energy produced by martensitic migration, the laser beam that propagates our of the knife tip is liable to shoot right out to Uranus and back. And to be honest, I'm not thrilled at the prospect.
