Mine recently became weapon collecting. I now have Legacy Arms Templar Sword, Templar Dagger and a Templar Ax.
Mind you. This is not toys. Like the knives in the kitchen, you should always be carefull. And not use real swords for training. There is specific swords in plastic and woods for this.
Well my point isn't just to brag, but to lighten a real issue. If you are overly focused on just one thing, you will runn out of ideas faster than if you engage in "other" things. That's why I've started this.
So what's your hobby?
