I was looking on KnifeNews last night, and links led to other links, and I came across an Aussie that has done a lot of semiscientific tests for edge retention, and I got fascinated. Lots of unexpected results, like 14c28n almost matching VG-10, and BD1 holding an edge not too far from 154cm. This is only one link, but he has a ton of these videos.
