Both knives in this set feature integrated ceramic sharpeners built into the protective sheath so you can conveniently sharpen them just before use. The sharpeners are suitable for most stainless steel blades (not for serrated or ceramic blades). The knives in this set have high-quality, stainless steel blades which are silicone-coated and nonstick. They have comfortable, ergonomic handles. Each has a nonslip base for safe sharpening and cutting.
