Summary
A Swiss-made stamped santoku with a 6.7 in Granton-fluted blade and black thermoplastic-elastomer handle, suited for cooks who want a light 4.2 oz knife for vegetables and boneless meat. Check the handle shape and edge upkeep before you buy: testers report a narrow neck near the blade and an edge that arrives less than fully sharp.
Strengths
- At 4.2 oz with a 1.81 mm spine, it feels light and agile for mincing herbs.
- Textured handle gives a secure grip that owners moving from slippery metal handles specifically seek.
- Slim spine slices without wedging, meeting the under 2 mm threshold testers link to clean onion cuts.
- NSF certified and ambidextrous for shared kitchens.
- Lifetime defect warranty with Swiss manufacture.
Weaknesses
- Independent testing found the edge felt dull from the beginning, and a store review for the same SKU reports blunting within a week.
- Controlled testing across seven Granton-edge knives found no reduction in sticking, calling the flutes unnecessary.
- Textured handle tapers to a narrow neck near the blade that testers describe as uncomfortable.
- Thickness and taper push the hand forward and block a pinch grip, especially for smaller hands, in owner reviews.
- Stamped construction stays sharp for less time than forged construction, per the manufacturer’s buying guide.
- Citrus, onions and tomatoes left on the blade can discolour or pit it, and air-drying can leave spots that lead to rust.
