The sharpness of a blade is manifested by its capability to cut. The
sword, when swung with the right precision, produces an acute effect which enables it to cut through materials that are softer than the blade itself with relative ease. However, considering a blade to be only razor-sharp to utilize the maximum potential of the sword is a flawed theory. In reality, the purpose for using that blade is more important as the reason behind using a sharp blade in the first place is to fulfill a specific purpose.
The Edge
If the edge of the blade is acute and flat, and it has concave sides, the sword will be able to slice with ease but it will be more delicate because of these properties. Such properties are advantageous for softer, dense targets that offer little to no resistance but will not fare well if used with harder targets such as a bamboo or
armors used in battle.
Sizeable
The blade for serving such purposes need to be more sizeable. Historically, this purpose was attained by modeling the blade with more niku; it was forged with a convex cross section instead of flat planes on the sides of the blade. The intent was to have a lesser acute-angled edge and supplementary supporting metal behind it to allow it to absorb more beating. This does not mean that a blade without niku is sharper but instead, the sharpness has been molded into the blade with a calculated purpose in mind.
Consistency
There are other factors that play a determinant role in the cutting power of the blade; the edge of the blade needs to consistent, straight and free of damage, and the steel must be resilient. Every sword undergoes damage to some degree when used over time. This damage adds up until the blade is not able to cut as well as it should.
The most conventional type of damage is scuffing when a blade is scratched by the target while cutting through it. This damage is merely cosmetic and can be fixed by using a mild abrasive. Other types of damage include rusting which is usually caused by negligence and poor maintenance. Rolled edges caused by incorrect alignment of the edge and hard targets is another damage caused to the blade. All of the above can negatively effect on the sharpness of the sword. Luckily, a well-made sword can be maintained and all the damages to the edge can be fixed by a professional. Chips, pitting and flat edges can be fixed as well. However, amateur handling of the sword can do permanent damage. Hence, it is highly advisable to go to a professional and avoid experimenting with the sword. Overall, maintenance is the key to the life of the sharpness of the sword.
Swords are shiny, eye-catching weapons which are great as a collector’s item and tasteful decorations. Whether you pick up your sword often or just leave them on a wall, it is very crucial to clean them regularly for maintenance. In this way, damage can be prevented and it will look their best.
