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. The proven high quality technology material POM-C forms handles which have great resistance to heat, wear and dishwasher detergents. Stellar Sabatier handles are crafted using solid spun one-piece rivets, spun flat under pressure which cannot work loose. Stellar Sabatier knives are dishwasher safe, but handwash is recommended.
