Convex Edge or Beveled Edge Shears

The difference between convex edge and beveled edge scissors
 
Q: What is the difference between convex edge shears and beveled edge shears? What is the best choice for haircutting?
 
A: When selecting a pair of haircutting shears, you may encounter the terms beveled edge and convex edge, which describe the specific blade geometry of the shears. Understanding these differences will help you make an informed decision based on your cutting style, comfort, and budget. Currently, approximately 80-90% of professional shears worldwide feature a beveled edge, making it the most common choice among stylists and barbers.
 
The term beveled edge refers to a distinct, angled cutting surface that is honed into the blades. If you examine a pair of beveled shears closely, you’ll notice that the blades slope gently before transitioning into a sharper angle near the cutting edge, typically around one millimeter from the tip (though this can vary depending on the shear size). This steep angle enhances cutting efficiency, allowing the blades to slice through hair more effortlessly than a flat-edged shear would. Due to their durability and widespread use, beveled edge shears are often called Germanic shears and are favored by many professionals for their reliability and ease of maintenance.
 
In contrast, convex edge shears (sometimes referred to as Japanese shears because of their origin) feature a smooth, curved backside on the blades rather than a sharp angle. Instead of a clearly defined bevel, the edge is precision-milled to an ultra-fine point, creating a thinner, razor-like cutting surface. This design allows the blades to glide through hair with exceptional smoothness, reducing friction and providing a cleaner cut. Although convex shears are less common than beveled shears, they have been growing in popularity among stylists who prioritize precision and effortless cutting performance.
 
As for which type is best, the answer largely depends on personal preference and practical considerations. Convex shears are widely regarded as the smoother-cutting option, offering a buttery feel when slicing through hair. However, their advanced manufacturing process makes them significantly more expensive than beveled shears. Additionally, convex blades are more delicate. Accidentally dropping them can easily damage the fine edge, and not all sharpening services are equipped to handle their unique curvature. Professional sharpening for convex shears tends to be costlier and requires a specialist to maintain their optimal performance.

On the other hand, beveled shears are generally more affordable and easier to maintain. Their sturdy construction makes them less prone to damage from everyday use, and sharpening services for beveled edges are more widely available and economical. That said, some stylists find the cutting experience with convex shears so superior that they are willing to invest in the higher cost and maintenance.
 
Ultimately, the best choice depends on your budget, cutting technique, and personal preference. If you prioritize durability and cost-effectiveness, beveled shears are an excellent option. But if you value ultra-smooth cutting performance and are willing to handle them with extra care, convex shears may be worth the investment. Consider trying both types if possible to determine which feels better in your hands and suits your cutting style.
