Actually, I could arrange for the Tank test. This would be rediculous, but funny. I don't think any of the handles would survive, but it would be interesting to see which if the blades end up looking like pretzels. What's your choice, M-60A-1-3 at 107,000 pounds or M1 at 125,000 pounds. Maybe put the knife on a bolder angled and let the tanks run over them to test the bend strength.
