Personally, I would never bother sharpening a utility knife blade. I consider those disposable (if you are talking the box-cutter type).
The drill bit sharpener has always puzzled me. It seems far too pricey unless you are sharpening professionally. Seems much quicker and cheaper with mini files.
And in addition to the price of the tormek, there is a learning curve. I've been sharpening with stones for decades. Had my tormek for 5 years. Took me a long time to get good with it and I still learn something almost every sharpening session.
