Here’s what I’ve used for about 30 years; https://www.leevalley.com/en-ca/shop/tools/sharpening/44884-sander-grinder. It was a lot cheaper back then but I had to put my own motor on it. I used a second hand washing machine motor. It still works great and can get new belts from them too. I use it for hooks, knives, chisels etc. It also has an attachment for doing long planer-type blades.
I had one of those , mounted it horizontally on the bench , built a jig for it and it was my primary knife sharpener in my shop , slow rpm is key to not heating up and lee valley and skookum tools had a great assortment of grits , hair splitting sharp
