Couteau de chef
The workhorse of the kitchen. A chef knife (and its Japanese equivalent, the gyuto) handles the widest range of prep of any blade you own — chopping, slicing, dicing and portioning. Ours are forged from Japanese VG10 and AUS-10 steel at roughly 60 HRC, so they take a keener edge and hold it longer than softer European steel. Sizes run 8 inches, with chef knife and sharpening steel box sets if you want the pair.
