I have used a cryogenic Hock since the early 80s and have been quite happy with it.
I lay my planes on their sides, and flip chisels over when laying them on my benches, unless there are a few fresh shavings I can set them on to isolate the cutting edges from the steel-wool dust and other abrasive crap on the 'wooden benchtop'.
Working as long as I have with the same tools and blades, you find they have become magnetized, and like to pick up whatever steel debris they can find.
