My other hobby is woodworking. Most has already been addressed, but a little more detail.
1st and 2nd pics are x-acto knife blades. 1st is keyhole saw for curved cuts. The 2nd are carving blades. Usually only good for soft woods such as basswood or balsa.
3rd are carving burrs, usually used with a flex shaft variable speed rotary tool. A favorite of decoy carvers to shape the wood fast.
4th are hand held contour sanding blocks. I use them on the furniture moldings I make.
5th is a sandpaper for a pneumatic sanding drum. You're missing the drum.
