What is the proper way to cut plastic wire ties?

Using flush-cut diagonal pliers to cut plastic wire ties is the recommended method because it provides a clean and flush cut, which minimizes the risk of sharp edges that can potentially snag on surfaces or cause injury. This tool is designed specifically for making precise cuts close to a surface without leaving any protruding ends, promoting safety and a neater appearance.

In contrast, using scissors may not yield a clean or flush cut and could result in frayed edges. Standard pliers, while capable of cutting, do not typically provide the same level of precision as diagonal cutting pliers. A utility knife is inappropriate for cutting wire ties because it's designed for slicing materials rather than making the precise, flush cuts needed for ties. Overall, flush-cut diagonal pliers offer the best combination of safety, neatness, and efficiency for this task.
