Why Scissors Have Different Blade Shape?

Scissors have different blade shapes to accommodate various cutting techniques, hair types, and desired outcomes. The blade shape plays a significant role in determining the precision, texture, and versatility of the scissors. Here are some common blade shapes and their purposes:

1. Straight Blade: Straight blade scissors have blades that are straight from the pivot to the tip. They provide a clean, precise cut and are commonly used for basic cutting techniques and creating sharp lines. Straight blade scissors are versatile and suitable for various hair types and styles.
2. Convex Blade: Convex blade scissors have a curved blade edge, similar to a clamshell shape. These scissors provide a smooth cutting action and are commonly used for advanced techniques, such as slide cutting, point cutting, and precision cutting. The convex blade shape allows for more control, softer blending, and seamless transitions.
3. Beveled Blade: Beveled blade scissors have an angled edge on one or both blades. This blade shape is often found in more affordable scissors and is suitable for basic cutting and general hair trimming. Beveled blade scissors are typically easier to maintain and sharpen.
4. Notched Blade: Notched blade scissors have small teeth or notches along the blade edge. The notches create texture and can be used for techniques like thinning or blending. Notched blade scissors are commonly used to remove bulk and add texture to the hair without removing excessive length.
5. Micro-Serrated Blade: Micro-serrated blade scissors have small serrations along the blade edge. The serrations help to grip the hair, making them particularly useful for cutting slippery or fine hair. Micro-serrated blades provide added control and prevent hair from slipping during cutting.
6. Specialty Blade Shapes: Some scissors have specialty blade shapes designed for specific purposes. For example, serrated blade scissors have multiple small serrations along the blade edge, ideal for cutting through thick or coarse hair. There are also specialty blades for specific techniques like texturizing or feathering, with unique blade shapes to achieve desired results.

Choosing the right blade shape depends on factors such as the cutting technique, hair type, desired outcome, and personal preference. Professional hairstylists often have a variety of scissor blade shapes in their toolkit to accommodate different cutting needs and styles. It's important to consider the specific requirements of your cutting tasks when selecting the appropriate blade shape for the best results.
