From very modest beginnings, Global has developed into one of the most successful brands of professional kitchen knives in the world. Still crafted by hand in Yoshikin's factory in Niigata, Japan, Global knives are still manufactured to extremely high and exacting standards. Features of Global knives
The two most innovative features of Global knives are their edge and the way they are balanced. The most important feature of any knife is its edge, and the Global edge is truly its signature. The majority of the Global knives are sharpened or ground on both sides of the blade, just like Western style knives. However, their edges are ground steeply to a point as illustrated in Fig. 1 below, and to an acute angle. This is in contrast to Western or European knives that use a bevelled edge (Fig. 2) - the straight edge results in a dramatically sharper knife which stays sharper longer. The edge on a Global knife is so large and prominent that it is easily seen with the naked eye and extends a quarter of an inch or more up from the tip of the knife.
To balance their knives, Global uses a hollow handle which is then filled with just the right amount of sand to create the correct balance. Global uses this method rather than using a full tang and a bolster to balance their knives for two reasons. First, it is far more precise than using a tang and a bolster. Second, Asian knives typically do not have bolsters, since they only serve as a hindrance to cutting and sharpening.
Other unique features of Global knives are their smooth contours and seamless, all stainless steel construction which eliminates food and dirt traps offering the ultimate in safety and hygiene.How they are made
Global knives are made from the finest high carbon stainless steel available for producing professional quality kitchen knives. Yoshikin uses its own proprietary stainless steel called CROMOVA 18 Stainless Steel and this material has been designed exclusively for Global knives. This steel is hard enough for Global knives to hold the steep, acute cutting edge and keep their edge for a long time...but soft enough so that it is not too difficult to sharpen them. The CRO in CROMOVA 18 stands for chromium and the 18 is the percentage of chromium in the steel. This high percentage of chromium contributes to Global's excellent stain resistance. Care should be taken to keep your Global knives stain and rust free. To learn how to care for your Global knives, please click on the Care Guide button above. The MO and VA in CROMOVA 18 stand for molybdenum and vanadium and these are two metallic elements that give a knife good edge retention.
It is often asked why Global knives stay sharp so long without sharpening. The combination of the elements molybdenum and vanadium is one reason, but also refer back to the diagrams above of the straight edge vs. the beveled edge. Now take a piece of paper and gradually push it up your screen, slowly covering the tips of the two edge types, simulating the knives getting dull after use. Even as the Global straight edge gets dull it is still much thinner, and, therefore, much sharper than the knife with the beveled edge.
