"Roman Landes and John Verhoeven have both done different tests with AEB-L. In CATRA testing Dr. Verhoeven found AEB-L to outcut 52100, 1086, and Wootz damascus. He also found AEB-L to be able to take a smaller edge radius than 52100 in controlled sharpening tests. Roman Landes found AEB-L to have greater edge stability, toughness, and wear resistance than 52100. Edge stability is a property that describes a steel's ability to hold a finely sharpened edge. 52100 is one of the most well respected carbon steels, and is well known for its small carbides, high toughness, and high edge stability, so it's impressive that AEB-L was able to beat it in these categories, while also having greater wear resistance and being a stainless steel. Many users have reported that AEB-L sharpens as easily as any other carbon steel they have used."
