Advantages of M390
----M390 steel is one of the most popular and best performing types of steel on the market, it features in sharpness retention. M390 is so wear and tear resistant it also properly maintains the shape of the edge. As such a knife made from M390 steel will retain its sharpness for a very long time. This means you don't have to sharpen your knife as often. Not only great because sharpening your knife takes time, but also because it means your knife will last longer. After all, the more often you sharpen your knife, the faster it will wear out. It is not possible to sharpen a blade over its full height: the blade will become too thick behind the edge. This means it won't be as easy to use.
----In addition to sharpness retention M390 has a few other fine qualities. It can be hardened to a relatively high hardness without it breaking quickly. This, however, doesn't mean that M390 is very tough. It does mean that M390, when compared to other types of steel, can be sharpened a little thinner.
----M390 is also relatively stainless. Because of the large amount of chrome rust won't stand a chance. Especially when compared to other hard types of steel that are known for their sharpness retention but can still be affected by rust.
