Looking on-line, it's pretty hard to discern meaningful differences in the high end "German" steak knives. Some are plain edged, others "hollow" edged, some have aluminum cases but, the real differences are lost in weak descriptions.
What high quality steak knives would you buy? Where would you shop? My price range is ~$100~$150 for 4 FWIW and I'm nowhere near a good knife store so online really is my only option.
