The Stellar Sabatier combination of Carbon-Chrome-Molybdenum and Vanadium Steel offers the advantages of easy sharpening with extended edge life and resistance to rust and stains. Each blade is fully forged from a single billet of top grade steel - not strip steel. Blades have a full length 'tang' which extends into the handle. The craftsman-ground edges will retain their sharpness through expert hardening and tempering. The perfect taper grinding of Stellar Sabatier blades produce a fine and very strong cutting edge unlike hollow ground blades which eventually become impossible to sharpen. Each Stellar Sabatier knife has a perfect join between the handle, bolster and blade - the hygiene requirement of top quality professional knives.
