Taken in the broader sense, the survival knife can be split into four or five significant constituents. Each of them is related to the other in the knife shape and what comes as striking is that some of the parts are more pronounced in some applications than with others. An attempt is being made here to bring out the defining aspects of each of the constituent elements and the relation that it holds in the broader action that the knife seeks to produce.
1. The Blade
Every knife and no matter the application happens to be based on the way the cutting blade is constructed as well as the material used to make the blade. Often steel is used when the sharp edges are to be done to the cutting side, but a drawback of steel blades is the sort of transmission of the shock as the cutting is done with the survival knife. Steel does have the property that it can be worked in so many different ways that all sorts of shapes and sizes are possible.
Some of the knives like the scouts’ knives have articulated blades which can be folded away into the handle after use. This provides an added element of safety and cuts out the possibility of accidents from happening.
2. The Handle
It is with the handle that most people get to use the cutting knife. There is an important function to the handle and the material used to make the handle, and that is to keep the force used in cutting and chopping from coming onto the users’ hands and arms. Unless done the right way, the design of the handle can influence the final user experience to a fair extent.
A lot of people, who are avid hunters and scouts, do use the handle to make an announcement of their exploits. There are the bands and cuts done into the wooden handles to denote critical happenings in the past.
3. The Serrations
Often it is seen that hunting knives have grooves or lines cut into the sides of the blades. These are used to add strength to the blade. The slots aims to focus the stress to specific points on the knife and once done the right way, helps better control the knife too. If a knife is used to cut meat and other game, then it would be to have the blade of the knife stiffened by applying a heat process.
4. Tempering the knife
The act of tempering the knife is nothing but heating the blade long enough and then subjecting it to a cooling process. Usually, the cooling action is much slower than the heating bit, and it is possible to have different operating characteristics to the knife by controlling the cooling sufficiently well. But the tempering, if not done just right, can be counterproductive in that the blade loses the flexibility and strength as well.
