When shopping for a quality tool, “take it down off the shelf and feel the weight,” Talbot advises. “A lightweight utility knife might be cheaper, but it might not feel as good in your hand.” Imagine using the tool: Is it substantial enough for you to grip firmly? Typically, a higher-quality tool will be little heavier than a substandard model.
There are exceptions, however. If a tool is used overhead—for example, when a wide taping knife is being used to smooth joint compound on ceilings—a heavy tool can be a burden. Hyde Tools understands this and has developed lighter taping knives in its Black & Silver line. They’re just as durable as all the company's tools, but you’ll be able to keep taping overhead a little longer without arm fatigue. Consider how you will be using the tool, and then factor in whether it’s the best weight for your needs.
