How does the wavy blade design of telescopic hedge shears improve pruning efficiency or effect?

Compared with ordinary straight blades, the wavy blades of telescopic hedge shears can provide a larger contact area when contacting branches. When pruning branches, the contact points between the blade and the branch increase, which means that the wavy blade can apply cutting force to multiple parts of the branch at the same time under the same cutting action. For example, when pruning a thicker branch, a straight blade may only be able to cut from one direction of the branch, requiring multiple cuts to complete; while the wavy blade has a large contact area, so it can cut off multiple parts of the branch in one cut, greatly reducing the number of cuts, thereby improving pruning efficiency.

The wavy undulating design allows the blade to have different cutting angles at different positions. This multi-angle cutting method can better adapt to the shape and growth direction of the branch. When encountering curved or irregular branches, the wavy blade can use its blade parts at different angles to cut more smoothly. In contrast, straight blades may need to constantly adjust the angle to complete the cut when facing irregular branches, while wavy blades can find the right cutting position more quickly, reducing adjustment time and thus increasing pruning speed.

The special shape of the wavy blade can make the cutting process smoother and more precise. When cutting branches, the wavy undulations can guide the blade to apply force more evenly, avoiding local cutting too deep or too shallow. The cross-section of the cut branches will be neater, without burrs or tears. Just like cutting with a precise scalpel, the wavy blade can ensure that the branches are cut neatly, making the trimmed hedge more beautiful.

Because the wavy blade can achieve a cleaner cut, it also causes relatively less damage to plant tissue. During the pruning process, if the cut is not neat, it may cause the plant wound to heal slowly or even cause infection. The neat cross-section after the wavy blade is cut is conducive to the rapid healing of the plant wound and reduces the risk of invasion of pests and diseases. At the same time, less damage also means that the plant can resume growth faster and maintain a healthy growth state, which is very important for the overall beauty and growth quality of the hedge.
