Basic chisels

[Uncle Alvah]

I am trying to gather up the things I need for my first Longrifle build.
I have a decent selection of straight chisels, but I was hoping to get a few recommendations for what other chisels you would more-or-less consider mandatory. I'm figuring on a  a rather plain rifle, no carving or anything like that.
What do I need to be adding to my chisel selection?
