Woah, thanks alot for all the replies guys!
There sure is alot of things to choose from, I'd like to stay in the tomohawk category though I think

since, well. its multi purpose. And still seem most lethal compared to weight. Those Fiskars axes are quite nice though... But somewhat expensive if you are going to stock up on them, and I imagine them to be VERY top heavy. And I asume if someone would break into my house, and see me in underwear with a tomohawk, and they STILL didnt run. That means they are very well ready to get into a lethal fight. And in that case I prefere to have a lethal weapon

If someone is ready to take my life I wouldnt care much if they get chopped a arm off in the process of trying to stop them (I would asume so atleast. I can ofcourse not talk for precicely how I would react before It happens)
Sorry if I am wrong but I just dont think a bat or axe handle wil do enough damage.
Its a whole other talk if you're just trying to defend yourself on the street, but when someone is in your house and doesnt run when you have noticed them. Then I'd asume they are ready to kill. And then I want to be ready aswell
It isnt realy much of a proplem with several of the same items around the house, since they would all be somewhat hidden in said room. And its not like the police would search my house after it would happen. Not right away atleast. So I'd only have to explain the one away I did it with. Somewhat hard to explain why you got a axe in your bedroom or bathroom though

got to think about that one. I didnt include the kitchen course I'd be within reach of a large enough knife there instead
Burningcort - Well, sadly a firearm here would land you several years in jail and its almost impossible to get hold of one ilegaly without being HA or such.
Also, the excuse that you use them for throwing doesnt work <.< its ilegal to own a throwing axe in denmark. Heck we cant even have a locking pocket knife. Its fun though. You can find lots of throwing axes to buy, but aslong they are marked as a normal axe they are perfectly legal. As soon you start throwing with it you can get in jail for it <.<
Thanks alot again!
