When it comes to Bushcrafting, a knife is an essential tool.
It is not only used for cutting and carving, but also for making fire, setting up tents, and many other tasks.
When choosing a bushcraft knife, there are several factors to consider, but one of the most important is the steel from which the blade is made.
In this article, we will delve into the question: Which steel is best suited for bushcraft knives?
Which steel for bushcraft knives?
The choice of the right steel for a bushcraft knife is crucial, as the blade does the majority of the work.
There are different types of steel to select from, but some are better suited for bushcraft knives than others.
Next, I will talk about HRC. HRC stands for Rockwell scale.
The Rockwell scale determines the hardness of metals and alloys by measuring the depth of penetration of a diamond cone. The lower the penetration depth, the higher the hardness indicated in HRC.

Hardness (HRC): Rockwell hardness of the steel.
Rust resistance (scale 1-5): 1 is the least rust resistant, 5 is the most.
Edge retention (scale 1-5): 1 is the least edge-retaining, 5 is the most.
Resharpenability (scale 1-5): 1 is the hardest to resharpen, 5 is the easiest.
Check out the graphic below. It shows how the different steel grades perform in four categories.
- Blue: rust resistance. The higher the bar, the better.
- Green: edge retention. A high bar means the knife stays sharp longer.
- Purple: Resharpenability. A high bar means the knife is easy to sharpen.
- Red dots: Hardness in HRC. A high point means more hardness.
Now let's move on to the most popular types of steel for bushcraft knives:
1. 1095 Carbon Steel
1095 carbon steel is a popular steel for bushcraft knives due to its high hardness (57-59 HRC) and toughness.
