Thread: Japanese Steel

I don't know if this applies but I found it doing a google on Tamahagne steel. Interesting reading one way or the other.

Its been my understanding that "Tamahagane" is usually used for the layered multi folded steel process the Japanese sword maker used. Similar to damascus steel, yet more refined in much higher layers ie; 2000 layers etc. or more. (damascus average 300 layers for good quality if forged into shape). I used to own a tamahagane made small tool knife I bought in Japan while visiting.

As far as scandinavian tool steel is concerned (I own many scandi knives) Krups tool steel is pretty much standard for tool steel in knives which can be tempered to a high rockwell of 60-61 , and silver steel for high end knives which hits rockwells of 61-62 (incredibly high). The high hardness of the steel in scandinavia is condusive to a very hard edge that can take and hold an incredibly sharp edge. US steel usually maxes out
at around 59 with an average of 57-58. The swedish prefer brusletto steel stainless, so I dont think swedish steel would be the choice of Japanese makers IMO. Rather Finland or Norwegian steel is more probable.

Ball bearing steel in the US is 52100 steel that comes in large bearing stock. These are usually forged to shape by mastersmiths in the US for incredible sharpness and toughness. 52100 is the boutique carbon steel of choice of the most renowned hand forger masters. I believe 52100 hits rockwels of 59-61

Therefore one can assume that for razors the higher the tempering capability of a steel is most desirable for an extremely sharp and lasting blade .
