The disk sander is quite a good tool for knife makers, it will get things sometimes a lot flatter than a so-so platen on the belt, I've got a little 150mm 6" one and its a very handy thing. You do have to be mindful of the angle of attack when grinding blade on one or it'll throw it off in some random direction and murder whatever it hits, kind of like buffing wheels in a lot of respects.

A Multitool sander might be an option if you're just getting started, need a reliable tool and there's a few variants like the 4x36, 2x36 and a 2x48
2x48 is a really good size for belt grinders on metal actually, it won't heat up to any appreciable level like a 2x72 does and belts for it are both cheaper and more available from big-box stores when you're living literally miles from fucking anywhere and have to get stuff shipped in. The most useful part though is that it fits on a standard bench grinder and if you get one in the 750-1000w range they'll pull damn near anything. The one like that photo tend to be pretty anemic things and the more load you throw on them, the shorter they live, which is mostly a pain in the dick to replace them again.
Plus once you're finished with using a belt grinder on your bench grinder, you can just put it back to stock and use it as intended- bench grinders tend to be fairly fucking robust things and keep on going for a fair while if they're even just a basic good one (ie- 20+ years!) but most wont have a speed control of course as that's a different breed of AC motor.
(there's also a few other options for these which have work rests and stuff too)

Just an option maybe before you leap into making a 2x72 with no welder, a welder is a handy thing to have anyway even if its a cheapo mig with fluxcore wire
