Kai is known for its high-quality Kai Shun kitchen knives. The Kai Wasabi series is also given great quality but is a bit more affordable. The Daido 1K6 stainless steel blade is sharpened thin to a hardness of 58 HRC. Because these knives don’t have a bolster the whole edge can be used and the entire length can be sharpened. The handle is made out of a combination of bamboo powder and polypropylene. This makes it durable and waterproof.
