My local Lidl had this sharpening station on offer recently for £15. It is able to sharpen drill bits, chisels, knives, and scissors. I think for the money it does a reasonably good job.
It is by no means the most precisely made bit of equipment but it does sharpen drill bits, chisels are sharpened very well. As for knives, it seems to give them a sharper edge although a knife with replaceable blades is still more practical.
