I bought these knives as a "starter set" for a budding chef. Whilst the blades are certainly sharp, the knives themselves do not have the heavy chunky feel I associate with a great quality cooks knife. They are not particularly well-balanced, and the slimline handle is not a comfortable fit in your hand. Despite the Sabatier branding, they feel flimsy, and are not of the quality i would expect from such a reputable manufacturer.
Still, you get what you pay for, I suppose, and these, whilst not cheap, are still relatively competitively priced.
