Thanks, Tom! I've never used D-2. I've played with 1095 when I first started, but beyond that, it's been AEB-L for all my leather knives. Here's an article (with more info than anybody would want or need) on AEB-L with some D-2 references and comparisons. https://knifesteelnerds.com/2019/03/04/all-about-aeb-l/
