Shoot them with a 22lr and work your way up to a Howitzer.

Take the small pieces, if you can find any, and load them into a 12 gauge shells. Fire them at armor plating. I highly recommend eye pro at minimum for this test. Then examine the marks left by the different blade fragments.

No point in doing the same old destruction test for the umteenth million time.

maybe you should just shave some paper with them instead of doing anything I ever tell you.
