I just use a grinding stone to sharpen our knifes. Takes a bit of getting used to but I can now sharpen them in a few minutes each. I don’t go for ultra sharp but sharp enough to slice through paper with little effort.
I just buy cheap knives and bin. I do have globals and a global stone which I use to use. I used the stone then a steel and it would get the knifes that sharp you could shave the hair off your arm with them. It’s how we use to test the sharpness in the kitchens.. https://richmondcookshop.co.uk/product_info.php?products_id=856 not a bad price..
