Only aggregate ratings are supplied, with a small sample showing five-star ratings. That is a limited positive signal, not enough to establish broader customer consensus or explain why people rated it well. Consider the practical trade-offs instead, especially the hand-wash requirement and the scabbard-dependent sharpening feature.
