Here's the bugger that fiired into the concrete floor!

Pictures of the little sucker that my belt grabbed and fired through my water bucket, carpet, carpet pad and stuck into the concrete floor. That was before heat treat, and the tip only deformed a tiny bit, so I was impressed (and glad my foot wasn't beneath the grinder at the time)!

Looks like a cool little knife to me. And, now you can brag that the knife was "Drop Tested".

Wonder how fast it was moving.... 1725 RPM motor on the fastest setting with step pulleys would give 3500 RPM. According to what I found online, that would mean the knife was going 104.12 MPH when it stuck into the concrete! Ouch!
