420HC in stock
Yes, particularly from Buck. 420HC is a high-carbon variant of 420 stainless with about 0.45 to 0.55% carbon and 13 to 14% chromium, run at 56 to 58 HRC in Buck's factory spec. Corrosion resistance is excellent, toughness is very good, edge retention is modest by modern standards, and it sharpens very easily.
420HC is a higher-carbon version of AISI 420 stainless. The verified steel records name Buck's decades-long proprietary heat treat as what sets Buck's 420HC apart from generic 420, and the 56 to 58 HRC range quoted here is Buck's own factory spec.
That is why a steel name alone tells you little. The same designation on two different knives is not the same steel in practice once the heat treat differs.
Toughness and corrosion resistance. The records rate its toughness very good, a big reason it remains popular for hard-use fixed blades, and place it among the more corrosion-resistant knife steels in common use. That is exactly what you want in a hunting knife that gets used wet, or a working fixed blade that occasionally gets abused.
It is also very easy to sharpen, which matters more in the field than a chart position does.
Edge retention. It will need sharpening sooner than D2, VG-10 or any powder steel. Buck sells the 110 in both 420HC and S30V, and 420HC vs S30V follows that step. That is a fair trade for how quickly it comes back and how well it resists damage.
If you sharpen your own knives, modest edge retention costs you less than a spec sheet suggests, because the edge comes back quickly.
