The lethality of a blade depends on various factors beyond just the type of steel used, such as its design, sharpness, and how it is used. Both stainless steel and high carbon steel blades can be lethal if used with intent to harm. Here's some information to consider:
Edge Retention and Sharpness: High carbon steel blades often have superior edge retention and can be sharpened to a finer edge compared to most stainless steel blades. A sharper blade can potentially cause deeper and more severe cuts or punctures.
Corrosion Resistance: Stainless steel blades are more resistant to corrosion than high carbon steel blades. This property makes stainless steel blades less prone to rusting or staining, which can affect the blade's performance and potentially introduce harmful contaminants into wounds.
Blade Strength and Durability: High carbon steel blades tend to be harder and have greater strength, allowing them to withstand more demanding tasks without chipping or breaking. However, stainless steel blades can still be sufficiently durable for most everyday uses.
Blade Design and Purpose: The overall design of the blade, including its shape, length, and point, can impact its lethality. Blades designed for combat or self-defense purposes, regardless of the steel type, are often optimized for inflicting serious injury. Conversely, kitchen knives or utility knives, which are commonly made from stainless steel, are primarily designed for cutting tasks rather than combat.
It's important to note that the legality and intent of using a blade to cause harm varies across jurisdictions, and using any type of blade against another person can have serious legal and ethical consequences.
If you have concerns about the lethality of a particular blade or its intended use, it is advisable to seek guidance from experts in the field, such as knife professionals, self-defense instructors, or legal authorities in your jurisdiction.
