Just be careful whacking anything but a T-rex with one. Back in the '70's most cops carried Kel-lite flashlights. More than one got into trouble in court after putting knurling marks in the noggin' of some bad guy with one. Got so bad that my department came out with a weight to number of D cells formula that could be carried, both Kel-lites and Mag-lites were too heavy, and therefore could not be carried. That stuck us with junky plastic lights 'til the Streamlite SL-20 came into being, the department OK'd those thanks to their superior lighting capability...
