Pro Balance Knives are revolutionary in concept and design. All Pro Balance Knives feature a hollow handle which can be opened to customise the weight by adding or removing small weights. If you like the sharpness of a true Japanese knife, but hate the weight of most Japanese knives, simply add in the included weights into the handle. By shifting the weights forwards or backwards you can alter the centre of balance of the knife which will either aid a pinch or hammer grip. The knife itself is no gimmick though and has an all S/S design and structure. The blade undergoes sub-zero treatment during the tempering stage to create an incredibly strong blade (made from German 1.4116 steel) with a +55 HRC rating, and hand sharpened to rival any Japanese brand. The knives slice through food effortlessly and all come with a special coloured end cap so you can tell which knife is which in the block. Always wash your knives by hand; dry thoroughly and never put them in a dishwasher. Knives should be stored in a block or other protective case to protect the blades and always kept out of reach of children.
