It takes an excellent edge with very little effort. This is one of its major advantages. It is very fine "grained" if you can speak of grains in a precipitation hardening steel. It is a pleasure to touch up an it gets very, very sharp. It is not very abrasion resistant, which is part of the reason why it is so easy to touch up, but very hard at the edge. On hard materials will low abrasion, such as wittling hardwood, it will hold up very well. On par, and perhaps even better than some of the top-end steels. On very abrasive material, such as cardboard, you will see a noticable difference though, in comparison to a highly abrasion resistant steel like S30V.
The Salt line is probably the line that is most rewarding to tinker with. It is not too expensive if you make a mistake and the grindability allows you to thin out the edge/blade even with hand tools without too much effort and H1 is one of those steels that will support a fairly accute edge (below 10 deg per side).
