Made of high-carbon tempered stainless steel. Then, fused with a thin layer of Titanium Nitrite to increase strength and hardness. The handles are made with Beech hardwood, with a flat bottom to sit flat on a table surface. The titanium-fused blades are three times harder steel for maximum performances, create a resilient cutting edge that stays sharp longer than the conventional carbon steel blades. The handles are soaked in pure Tung oil for water, slip, and mold resistance. They are made in Xiem’s shop in Garden Grove, California with domestic and international materials.
