Ever have the point kink at the tip due to hitting a rock? Not often but often enough to check even with chemically sharpened hooks. Same goes for pulling free from a snag and finding the gap wider. A wide gap is worse than a slightly dulled hook and guarantees fish lost. (I know, softer metal hooks are a no no but they catch fish after fish and the jigs can be released from many underwater snags. Pliers are a must to close the gap!)
