How-to
How to sharpen a knife on a whetstone: grit order, the 15 to 20 degree angle, honing afterward and a safe paper test, plus when pull sharpeners make sense.
A dull knife is the one more likely to cut the cook, because it takes more force to push through food. Sharpening fixes that, but the job only goes well when the tool matches the knife and the angle stays steady from the first pass to the last.

Sharpening takes metal off and reshapes the edge, turning a rounded, worn profile back into a narrow, fine one. Honing is upkeep: a honing rod realigns the metal and works small nicks and flat spots out of an edge that is already sharp.
Because honing does not remove steel, it cannot rescue a truly dull blade. It belongs between sharpenings, and again right after one, never in place of them.
Three tools do the work, and the whetstone is the one worth learning. With a little practice it can leave a knife sharper than it was new, which electric models may not match. Pull and electric sharpeners suit anyone who wants the quickest fix for very dull knives, and the usual advice is to match the sharpener's brand to the knife's. Thin boning and fillet blades are common in poultry prep, and boning knife vs fillet knife sets out how the two differ.
Two stones cover most dull knives: a coarse one to reshape the edge and a finer one to refine it. A knife that only needs upkeep can manage with a single finer stone.
Finish by honing on a leather strop or a steel or ceramic rod, then wipe the blade down to clear any steel residue. To test the result, wash and dry the knife and try slicing down through a sheet of paper held loosely in the air. If it snags, go back to the stone for a few more passes. Never drag a fingertip across the edge to check it.
Storage protects the work: a knife block, a magnetic strip or guard covers keep the edge from dulling against other tools. The knife to cut raw chicken comparison lists the boning, fillet and chef's-style knives that suit poultry prep.
Yes, but slowly. With regular use, a metal honing rod can last potentially decades before it needs replacing.
Technique is only one cause. Cheaper stainless steel is soft and does not hold an edge well, so a harder steel or a steeper sharpening angle can help. Handling matters too: use the right knife for each task and avoid glass or stone cutting boards.
