I know about the DA Half-Rounds which are pure nickel. Fodera makes a Compressed Round in SS. GHS makes the Pressurewound Flats, which aren't really a Flat.. The Ken Smith Slick Round / Ground Wound appears to an Alloy 52 type. These appear to be smoother than their Compressors. I'm looking for brightness comparisions, life expectancy. Preference is for true Groundwound types, rather than compressed type. Anything like this in stainless? Thoughts?
