You are the age that I started making knifes.
This was my first tool and is still a mainstay in the shop.

If you mount a piece of 3/16th X 4 inch X the table length steel plate under the belt to raise it you can flat grind with ease.
The disc is for profiling a blade and when the table is raised the end roller will do additional profiling for shaping full and hidden tang knives. Both of these get a lot of use for handles also. Belts are readily available in various grits.
