They cut carbon fiber and stainless steel using water jet saws. A pressure washer delivers a non-trivial fraction of that stream. I would have known to keep it away from human flesh.

I knew about water cutters for concrete and such, but I didn’t realize an ordinary household pressure washer could have that much force. I’ll have a little more respect for those things from now on.

I used to work for Hotsy Corp, and their washers run from 1200 psi up to 3000 psi. I once made a pass across a 2×4 with a 3000 psi model, and left a cut 1/2″ wide and 1/4″ deep. Even the smaller ones will cut (slowly) through a plastic barrel and excavate a pit in an asphalt parking lot.
Fun toys.
