Welcome To LP101 !!
Well to start off, do you know anything about locks ? i would strongly suggest that you read the MIT LockPicking Guide and that you understand the basics of locks, then we can move on.
And to anwser your question, yes, you can make picks, tension wrenchs and many other things made from stuff from your home. I'll dig up a couple of posts that you might be interseted in friend..
