Painstakingly polished by hand and forged under high-pressure, the sharp concave blade snugly fits the curve of the nail to deliver a stable, firm cut. The spring separates on one side from the handle, and this in combination with an innovative new cylinder spring ensures that the tip of the blade opens wide to easily accommodate curled nails and irregularly shaped toenails. The clearly visible tips of the blades make the Suwada Nail Nippers simple to use even for those who are not accustomed to using nippers.
