I think the Police Pen is completely different. The Fireman's Pen is a bit bulky but it's a sturdy and or heavy pen. The Policeman Pen is lighter and the click mechanism feels a little on the cheap side. I like the Fireman Pen but I'm having trouble keeping the logo centered with the axe. The threaded piece that screws the blank into the top is giving me trouble. If you use wood for the blank I think you'd be ok. The threaded piece screws all the way into the top part of the pen so if you hand screw the adapter in first then press on the tube it will align but when you unscrew the tube there will be a gap between the tube and adapter. If you press the adapter to the tube first it will be tough to align everything but doable. My issue is the alumilite isn't seating well against the metal top so depending on the amount of pressure used to tighten the top depends on the alignment. I'm also worried about the pressure from the pen top will eventually cause the resin to separate. I do like the kit, I'm not sure about using this type of blank with it.
