What Is the Best Nail Clipper for Thick Toenails?
Sep 24, 2026
For thickened toenails, a nail nipper is often the most practical cutting tool. Mayo Clinic specifically recommends nail nippers for thickened toenails because they are easy to grip and control, and because the open jaws make it possible to take small straight cuts across the nail.
The most important features are not brand names. Look at jaw opening, leverage, visibility of the cutting edge and whether the tool lets you cut the nail in small controlled sections without forcing it.
Why can a nail nipper work better on a thick toenail?
A lever-style clipper has a fixed opening. If a thick nail barely fits inside it, the tool may compress the nail or require excessive force before the edges can close.
A nail nipper uses open jaws and two handles. That layout makes it easier to position only a small part of the nail between the cutting edges and work progressively across the nail.
What should you look for?
- Enough blade opening: the nail should fit without being forced between the edges.
- Useful leverage: a larger handle or longer effective lever can reduce the hand force needed.
- Good visibility: you should be able to see where the jaws meet the nail.
- Stable blade alignment: the two cutting edges should work together rather than pinch unevenly.
- A shape you can control: especially important when trimming toenails straight across.
What does SUWADA recommend for thickened nails?
SUWADA says its nail nippers can cut thickened or tough nails and recommends its Large size for thickened nails. The company explains that the larger model benefits from greater leverage and can cut a thick nail with less effort than the Small size.
Its current nipper design can also open much wider than in normal use. SUWADA warns, however, not to cut a thick nail in one large bite; it recommends cutting bit by bit to reduce the risk of cracking the nail or damaging the blade edge.
Is the strongest possible cutter always better?
No. A tool still has to fit the nail and the user's hand. A very large tool can be harder to position if visibility or hand control is limited. The best choice is the one that gives enough opening and leverage without sacrificing control.

When should you not cut a thick toenail yourself?
Mayo Clinic advises extra caution if you have diabetes, poor circulation or reduced sensation in the feet. It also recommends contacting a healthcare professional if the nail keeps getting thicker, becomes painful, or you do not think you can trim it safely yourself.
A thicker or stronger tool is not a treatment for the reason a nail has changed.
