do what you want to dude. are you planning on selling? going big? probably not i would guess, so it's for you, and you alone. therefore, be personal, be creative, be fun. in other words, don't use any of these ideas. use what makes sense and sounds good to you.
i love horror movies. specifically old school classics, like the texas chainsaw massacare, evil dead, dead alive, etc.
chainsaw brewing worked for me. another reason i went with this, and you'll want to keep in mind when coming up with your own name, is it has good visual appeal to me, with the crossed chainsaws, and also has lots of fun possiblities of beer names that goes well with the theme, such as "death by dunkel", "the bitter end", "blood, guts, and hefeweizen", etc.
