First Blood Knife

First Blood bowie knife. 440c and not 420j2 like United cutlery. 14 inch overall and 9 inch blade.The 400 SERIES:

420 Steel – Has about .38% carbon. The low carbon content means that this steel is very soft, and doesn’t hold an edge well. It is low quality, low cost material. Many cheap knives tend to be made of this material because of its cost. Blades made from this material need to be sharpened frequently, and often chip. On the bright side, all 420 stainless steel is extremely rust resistant. This means that one of the best uses for this material is to make diving knives because of their constant contact with saltwater. Sometimes, you will also see 420J. 420J is the lowest quality 420 steel, but is also the most rust resistant.

440 Steel – There are three different types of 440 steel, the hardest part of telling them apart is that often steel makers mark 440 on the tang of the blade and not the letter grade. This is especially true when it is one of the lower grades. This has led certain knife manufacturers to rename 440C as other things in order to differentiate the quality of the product.

440A Steel – Has a carbon content range of .65-.75%. This is a low cost stainless steel. It is the most rust resistant of 440 steel, and 440C is the least rust resistant of the three. However, the 400 series are some of the most rust resistant knives out there.

440B Steel – Very similar to 440A but has a higher carbon content range (.75-.95%).

440C Steel – This has a carbon content range between .95-1.20%. This is considered a higher end stainless steel. This alloy is one of the most common in knives. It is wear resistant, and it is a hard steel.
