Hello, I am a Scoutmaster here in NY and would like to introduce the Tomahawk to the troop... I just received my new Cold Steel TH and thought for the money it would be a great tool for the scouts... Since I am new to the tool can someone please tell me the best way to secure the head to the handle? I have put many an axe head on but I thought there must be a reason the tomahawks come unsecured. Thanks much!
