There are also innovations in knife technology. Ever-improving alloys for the blade steel enable a dynamic increase in the service life of the blade – up to 60 times that of the so-called Swedish steel blade! HSS knives with 18 percent tungsten content are the most frequently used knives in paper guillotines worldwide and have a 4-fold service life. In addition to a good price/performance ratio, their advantage is that they can be used without any problems when cutting common types of material. Thanks to their fine-grain quality, TCT knives achieve up to 10 times longer service life and are suitable for use with a wide range of cutting materials. LONGLIFE knives are a further development of the carbide knife described above, but in which a superfine grain carbide is used. This achieves up to 20 times longer tool life. GENESIS knives are characterized by a service life increase by a factor of 40. The ultra-fine grain carbide used for production is suitable for cutting paper, cardboard and very hard materials. VITECH knives are regarded as a benchmark, are an exclusive Hagedorn product and achieve unsurpassed cutting performance. In terms of service life, completely new dimensions are achieved: a 60-fold increase in service life compared to Swedish steel is the most common experience in the everyday work of users.
