Some 20 years ago I made with a great effort some chisels (and plane blades) of A2 steel. The intention was to have them for paring so they were sharpened to 25 deg.
As a lot of people have commented, A2 has poor edge retention at low angles so they they have sadly not been used so often.
Yesterday I tried to unicorn-sharpen them. Got a shiny nano bevel so hopefully they should be ok. Made some tests and they are sharp but it is too early to brag about the edge retention.
