Well yes, the whole thing is the striker, but that part must have a name. I've seen the front of the striker around the actual firing pin referred to as the shoulder, and I've seen the hook referred to as the foot. Not sure if either is correct. Not a big deal, but I like to use correct terms wherever possible.
I gotcha now.
Yes I would call that the foot.
Yes I have heard certain parts called the nose, body, foot, face, and top face.
That's about it for me.
