The G-21 is a classically shaped boning knife and is considered to be the standard boning knife in the Global series, it is certainly the best selling Boning knife. The knife has a long narrow blade with is tapered to a very fine point. This allows the user to work round the bones in joints of beef, lamp or pork and cut out a sizable piece of meat.

The blade is also flexible, which is great for getting under the skin and filleting fish. There are quite a few boning and filleting knives in the Global range, but the G-21 has a bolster, this is useful where working with raw meat or fish can make the knife slippy, it helps to prevent any unfortunate accidents. There is also a fully forged version of the knife, the GF-31.
