The G-9 is Global's classically shaped bread knife. It is a specialist knife, really for use with bread only. The teeth are made to saw through the crust of bread but could also be used for some tough meats, for example crackling. The funny thing is, the Japanese do not really eat bread and so it is one of those products that they never really understood! If you look closely at the knife blade you will see that on the face of the knife, the teeth have a chamber whilst on the back of the knife, the face is flat. When you cut into bread, you will automatically cut inwards in a curve rather than straight down and the chamber is there to help correct this so that your slicers will be more of a similar thickness all the way through. Whilst the G-9 can be used by left handers, the set up is right handed. Global can provide left handed bread knives on request. There is also a fluted version, the G-68.
We sometimes get asked from time to time, whether you can sharpen a bread knife. In our opinion you cannot and manufacturers that say their sharpeners can sharpen a bread knife are probably not correct. So please do not try and sharpen your Global G-9 Bread Knife!
