This tough steel is widely used by custom knife makers for a good reason. It has a high carbon content and produces a durable and relatively easy to sharpen knife with very good edge retention.
15n20 Steel
Mostly used for saw blades, this high nickel alloy is paired with UHB20c to produce a well beloved Damascus blade. Standing alone, it is corrosion resistant and can hold an edge reasonably well.
Gyuto
The Gyuto is the Japanese version of a Western chef's knife which is an all purpose knife but is thinner, lightweight and maintains a longer edge retention. Compared to its European style counterpart which has a belly and is used in a rocking style motion, a gyuto has a flatter profile and is used with a push cutting motion. The gyuto very well shines on precision cuts but because it is usually thin care must be taken to avoid chipping.
Isasmedjan
My name is Jonas Johnsson and I run Isasmedjan.
I don´t remember when my interest for blacksmithing started but it got a serious boost about 8 years ago when I took a week course in basic blacksmithing at Ryfors bruk here in Sweden, the teacher was Gustav Thane, one of Sweden's most renowned blacksmiths.
It took a couple of years before I could setup my own small forge, I now have my shop in a small garage next to my house, there I have learned this craft by trail and error
Since autumn 2016 I have run Isasmedjan part time as a small business next to my day job in the marine business.
I have gone to almost exclusively forge and make knives, mostly chef knives with traditional Japanese profiles but also hunting knives and art knives. I also forge blades which I sell to Scandinavian knifemakers.
I take pride in creating functional pieces of art and I am constantly seeking inspiration and knowledge about making the best knife possible not only suitable for it´s task but also pleasant to the eye.
