As I said in the title, it'd make more sense if you knew the lore. You'd also have to like older guys and have a thing for knives (which I do). If you want, I can give a full image of him...
I don't have a fetish. I just like knives. Having a fetish implies that you're sexually drawn to the object and/or want to use it improperly in a sexual manner. Which does not apply to me. However, I would gladly stab someone if given a reason to. But not in a sexual manner. How is being fascinated by knives suddenly a sex thing, I will never understand. Not that I want to.
