How do I sharpen and care for a VG10W knife?

VG10W sharpens about as readily as VG10. The tungsten precipitates hard, fine carbides that bring wear resistance without costing you ease of sharpening. On a whetstone it behaves like a conventional stainless: responsive, pleasant to raise an edge on, no exotic stones required.

Care is stainless-basic and takes seconds. At 15% chromium it is stainless rather than stain-proof. Rinse the blade and wipe it dry after use, wipe it dry again before it goes away, store it dry, and keep it out of the dishwasher. Like any high-carbon stainless it can spot if it is left wet with acidic food sitting on the edge, and a humid or coastal kitchen makes that likelier. When the edge finally dulls, bring the knife in — K&S sharpens and re-profiles in-store, which beats fighting a hard edge on the wrong stone.
