Global has a reputation for excellence in cutlery. Sai is Global's flagship line for those who want the best they have to offer. The Sai line has a more ergonomic handle to make working with them even more delightful! The blade is made of harder steel than other Global knives. The blade is clad in 2 layers of SUS410 stainless steel to protect the hard steel core. The exterior steel is hammered resulting in a beautiful blade that keeps food from sticking to it. The blade itself is sharpened to an amazingly sharp 12.5 degree angle on each side, allowing it to glide effortlessly through food.
