How often to sharpen
For a household that cooks most days, every three to six months. For a kitchen that goes through crates of produce or a lot of citrus, closer to three. For a knife that comes out twice a month, once a year is fine.
The better test than a calendar is a tomato. Set the edge on the skin without pressing and draw it back once. If it bites and goes through, the knife is fine. If it skids across the skin and you find yourself pushing, it is ready for the stones — that is the same test every blade gets here before it is wrapped for return.
A honing rod is not a sharpener
This is the most useful thing on the page, and almost everyone has it backwards. The steel rod that came with the knife block does not sharpen anything. It removes no meaningful metal. What it does is straighten an edge that has rolled over to one side under use — and a rolled edge feels exactly like a dull one.
So the rod buys you weeks between real sharpenings, and it stops working entirely once the edge is genuinely worn away rather than bent. A few light passes per side, at roughly the angle of the bevel, before or after cooking. If honing stops making a difference, the knife needs stones, not more rod.
Cutting boards, in order of preference
End-grain wood is the kindest surface there is — the fibres part and close around the edge. Edge-grain wood is close behind, and good plastic is perfectly fine and dishwasher-safe.
Glass, granite, marble and ceramic destroy edges. Every one of them is harder than knife steel, so the blade loses the argument on contact; a single meal chopped on a glass board can undo a sharpening. The same goes for cutting on a plate, or scraping the board with the edge to sweep food off — turn the knife over and use the spine.
The dishwasher, and the drawer
Dishwashers ruin knives three ways at once: the detergent is abrasive and alkaline enough to dull and stain the steel, the heat cycle can loosen or crack a handle, and the blade knocks against the rack and everything else in the load for an hour. Wash a knife by hand in warm water, dry it immediately, and put it away dry.
Loose in a drawer is the other quiet killer — every edge in there grinds against every other. A magnetic strip, a block, or even a cheap plastic edge guard costs a few dollars and saves the sharpening.
When it is past habits
Chips, a snapped tip, a rolled edge that will not come back on the rod, or a blade that has been through a grinder and no longer holds anything — those want stones and a hand, not a better routine.
