Mac & Katana contemporary kitchen knives were born from the ancient, samurai tradition. They combine revolutionary sharpness and durability with a innovative design for cutting efficiency and safety. These are the sharpest, most rugged, multi-use kitchen knives ever made for home or professional use...and they never need sharpening, just occasionally touch-up by passing the cutting blade across a ceramic sharpening rod and the knives will hold their sharpness for years and years. Beautiful, enduring and safe; they are uniquely designed to keep your fingers clear of the cutting board. Each knife's handle is bonded to the steel, a masterpiece of precision and superb craftsmanship. With the proper treatment and good care, these knives will last a lifetime.
