Our Heavy duty #209 Barrel Spring Nail cutter features a gentle curve on the blade. The sharp curved blades meet at tips of nails giving a detailed and smooth cut to the nail. This cutter comes with a safety lock which prevents accidental injury and allows the tool to be stored safely. Another feature is the non-slip grooved texture on the handles which allows a comfortable grip while the tool is in use. This Cutter comes with a Barrel Spring which allows perfect tension to the handles without any need for re-setting.
