What you should know about knives

The tang

 
The tang is the part of the blade which extends into the handle. There are two different types: the concealed tang (e.g. TWIN® Four Star II series) and the exposed tang (TWIN® Pro "S" series). Concerning the latter, a distinction is made between a full, half and quarter tang, depending on its length. Another example of exposed tang can be found in the TWIN® Cuisine series which has full tang but no rivets. The concealed tang is cast into the plastic handle and is safely secured with synthetic resin. The exposed tang´s rivets have the purpose of connecting the handle or scales with the tang.

User-friendliness through ergonomic design

Outstanding design combined with perfect functionality. The shape of the handle determines whether a knife feels comfortable and is easy to use. To a large extent, an ergonomically shaped handle fits the natural shape of the hand. When you pick up a knife you can quickly tell whether it suits you. ZWILLING J.A. HENCKELS pays particular attention to combine outstanding design with ergonomic principles.

The balance of a knife or the proper distribution of weight between the handle and the blade, plays an important role. To be able to use the knife for a prolonged period of time without causing discomfort or strain, the handle must be well shaped and neatly finished. A well designed handle has a distinct finger guard to give the hand a secure grip. The finger guard is either integrated into the handle or, in the case of top quality knives, designed as a steel part (bolster). Following the improvements in properties of plastic compound over the years - particularly under hygienic aspects - polypropylene handles have increasingly replaced wooden handles.

Polypropylene handles have a number of advantages: impact and shock resistance; best possible hygiene due to the smooth and pore free surface; dishwasher-safe.
