Sharp like a high-quality disposable razor.
Yet even the best blade steels have a limit to how sharp “sharp” is. Under high magnification, even the best of commercial scalpel blades look like a rip saw.
Want REALLY sharp? Then you have to transition to obsidian stone blades. The best steel scalpel blades are on the order of 300 angstroms wide, right on the finest edge. A typical obsidian edge is 30 angstroms. They will cut a single cell cleanly in half. They are in limited surgical use but are very brittle, very expensive ($100 per) and the edges are so fine that just about any side loading can chip or break that edge.

At present, very sharp because the disposable blades are used once and then discarded.
In the old days knives had to be sharpened from time to time, so not always so sharp after some time.
