Consider a tool like a kitchen knife. Right out of the packaging, it’s razor-sharp and can cut through everything with ease. Over time, however, the blade dulls and needs to either be sharpened or replaced. Dog nail clippers are very much the same. Depending on how often you use them, as well as how tough your dog’s nails are, you might find yourself having to replace them more or less often. Fortunately, the low price point of these tools and their general durability means that you’re not going to be wasting money.
