Se parliamo di prestazioni pure di taglio l'YXR7 praticamente non ha rivali... sono curioso di vedere i nuovi acciai della Hitachi che sta sperimentando sempre rockstead _________________ IMPORTANTE: "Non ascoltate pharadin tanto e' leso"
...per chi non lo conosce già ci sono maggiorni informazioni sull'acciaio dal loro sito:
Steel material
The steel materials that we are currently using are carbon steel YXR7 and stainless steel ZDP189. Both of these are cutlery steel materials made by Hitachi Metals Ltd. YXR7 (matrix high speed tool steel) A high-level steel material with wonderful properties, with a hardness of around HRc65 and very tough. These factors prevent blade nicks even after cutting and striking dried bamboo. However, because it is carbon steel it can rust, but this one drawback can be overcome by the ROCKSTEAD KNIFE mirror finish. Still we will recommend the blade be wiped with cloth after use. Although we coat with DLC to prevent rust, DLC can be worn off with use in the tip of the blade. So we wiping as mentioned above.ZDP189(powder stainless)A high carbon stainless steel specially produced for cutlery. The excellent hardness of HRc67 is made possible by introducing more carbon than can be contained in dissolution steel. It is a steel material that reaches the epitome of nanotech technology. We are using clad steel of ZDP189 sandwiched by ATS34, or ZDP189 alone.
Function
We are demonstrating the ROCKSTEAD knife in knife shows all over the world. After cutting φ25mm Manila rope (hemp) 1000 times, you can slice paper with this ZDP189 blade, made possible due its high hardness of HRc67. After cutting and striking dried bamboo about 500 times, you can slice paper with the YXR7 blade. The USA magazine Tactical Knife set up an experiment and continuously cut cardboard for three months with our knife (Beetle DLC) and reported that the sharpness had not deteriorated. _________________ :moose:
L'acciaio è di qualità? Beh, Indy, secondo me i rockstead sono la ferrari dei chiudibili industriali...
credo tu abbia ragione, ma non sono esperto di acciai, quindi chiedo sempre info a chi ne sa più di me sperando prima o poi di arrivare a capirne qualcosa _________________ :moose:
