I've heard that 1095 takes a differential heat treatment better than 1084 and 1084 is a better steel for a beginner to start with but what advantage does 1095 have over 1084 ? A little more carbon and maybe a little harder blade in the end. Please school me if you would.
I think that's exactly the difference. 1084 is more forgiving in the heat-treat than 1095, so it's easier to get a good blade. 1095 has that little bit of extra carbon (and I think some vanadium) which (potentially) gives it better edge holding and hardness. I think it's a case of either will make a good knife for the average maker, but someone who really knows their heat treating can see a big difference choosing 1095.
The biggest difference I have seen is a 1095 blade will show a hamon easier. I have used both but I prefer 1084 unless I want a hamon. Rick Marchand likes to use 1084 for its toughness that says a lot there.
I like how hard you can get 1095. I haven't used it a lot but the knives I've done in 1095 cut really nicely.
