If you needed just one knife for your kitchen go for a quality chefs knife and if you are going for Global buy the G-2. The G-2 is the best-selling Japanese kitchen knife ever made! It can slice, dice, chop, and really do anything that you need. A multi-purpose all round blade that is included in virtually every knife set produced. It has won dozens of awards over the years testifying to the popularity of the blade. Global (represented by the G-2) has won the Which? Best Knife category 3 times in a row.
The GS-5 is the little brother of the G-5 vegetable chopper, with the same shape of blade in a smaller proportion. These knives take their inspiration from Japanese Usaba (Vegetable Knives), the relatively flat parts of the blade are designed to chop through fruit and vegetables and come into full contact with the chopping board and give a clean cut. The front of the blades are more curved like a chef's knife, to allow the knife to be rocked gently forward after each cut and encourage good technique.
The GS-38 is a beautiful little paring knife useful for lots of little tasks in the kitchen. It is the hollow handle alternative to the GSF-15 and often found in more recent sets
