Shirogami 2 (White 2) vs VG-10
Quick answer
Shirogami 2 (White 2) is the harder steel at 61 to 63 HRC, so it holds an edge longer and is more prone to chipping. Shirogami 2 (White 2) is the tougher of the two and comes back more easily. If you sharpen on a whetstone, take Shirogami 2 (White 2); if you rely on a honing rod, take Shirogami 2 (White 2).
Hardness figures are published by the makers. The comparative scores are relative rankings rather than measurements.

| Origin | Japanese | Japanese |
| Hardness | 61 to 63 HRC | 60 to 61 HRC |
| Stainless | No, it will patina and rust | Yes |
| Edge retention | 4/5 | 4/5 |
| Toughness | 3/5 | 3/5 |
| Corrosion resistance | 1/5 | 5/5 |
| Ease of sharpening | 5/5 | 3/5 |

The short answer
Shirogami 2 (White 2) is harder, at 61 to 63 HRC against 60 to 61. That means it holds a working edge for longer and that it fails by chipping rather than rolling when it meets a bone or a frozen edge. Shirogami 2 (White 2) is the more forgiving of the two.
Neither is better in the abstract. The right one depends almost entirely on how you maintain knives. Someone with a whetstone and the patience to use it gets real value from the harder steel. Someone who runs a rod over the knife once a week and never does anything else is better served by the softer one, which will actually be sharp more of the time.
What Shirogami 2 (White 2) is like to live with
A very pure carbon steel that takes the keenest edge of anything here and sharpens beautifully. It also rusts: it will patina within a day and will spot if left wet, so it is wiped dry after every single use.
It is a carbon steel, so it patinas within days and rusts if left wet. Wipe it dry after every use. Sharpening scores 5 out of 5, meaning it comes back quickly on almost any abrasive.
What VG-10 is like to live with
The benchmark premium Japanese stainless. It takes a very fine edge and holds it, and at 60 to 61 HRC it will chip if used on bone or a frozen edge.
As a stainless steel with a corrosion score of 5 out of 5, it handles ordinary kitchen use without trouble. Sharpening scores 3 out of 5, meaning it needs a proper stone and real technique.
The trade underneath both of them
Hardness, edge retention, toughness and ease of sharpening are not four independent qualities that a good steel maximises. They trade against each other. Adding carbon and hardening further gives a finer, more wear-resistant edge and makes the steel more brittle and harder to abrade. Every kitchen steel is a chosen point on that curve, and the makers who use these alloys chose different points on purpose.
Geometry matters at least as much. How thin the blade is behind the edge, and the angle it is ground to, decide how a knife feels in the cut far more than the alloy does. German knives are typically ground about 14 to 20 degrees per side and Japanese double-bevel knives about 10 to 16, and that difference is more noticeable in the hand than the difference between these two steels.

Common questions
Which holds an edge longer, Shirogami 2 (White 2) or VG-10?
Shirogami 2 (White 2), scoring 4 out of 5 against 4. Edge retention tracks hardness closely, and Shirogami 2 (White 2) is the harder of the two at 61 to 63 HRC. The cost of that retention is that it chips rather than rolls when it meets something hard.
Which is easier to sharpen?
Shirogami 2 (White 2), at 5 out of 5 against 3. This matters more than most buyers expect: a steel that is quick to bring back is sharp more often in practice than one that holds an edge longer but gets neglected because sharpening it is a project.
Which is better for a first good knife?
Shirogami 2 (White 2). A first good knife should forgive mistakes: meeting a bone, a slightly wrong sharpening angle, being left in the sink. Toughness and easy sharpening deliver that. Edge retention becomes worth paying for once you have the skill and the stone to restore the edge.
Does either one rust?
Shirogami 2 (White 2) will. It is a carbon steel with minimal chromium, so it develops a grey patina within days and spots with orange rust if left wet. That is expected behaviour rather than a fault, and it is prevented by wiping the blade dry immediately after every use.
Is the more expensive steel worth it?
Only if your maintenance habits match it. Premium steel in the hands of someone who never sharpens is an expensive blunt knife within a year, because it eventually dulls like everything else and is harder to restore. The upgrade that reliably improves daily cooking is a whetstone and the willingness to use it, and that upgrade costs less than either knife.
