Here’s what that hole is really for:
🔩 1️⃣ Keychain Attachment (Primary Purpose)
On most lever-style nail clippers, the small round hole at the end of the metal lever is designed to:
-
Attach to a key ring
-
Hang on a hook
-
Connect to a travel kit
That’s its main, intentional design function.
🔧 2️⃣ Built-In Cleaning Tool (On Some Models)
On certain clippers, especially larger ones:
-
The small metal nail file attached to the clipper can swivel out.
-
The pointed tip is meant to clean under nails.
-
The hole allows that piece to pivot or be secured.
This depends on the clipper style.
🔄 3️⃣ Lever Removal/Replacement
The hole also plays a role in how the lever:
-
Locks into place
-
Rotates when flipped around
-
Secures tension for cutting
If you’ve ever flipped the lever 180° to reattach it — that hole is part of the mechanism.
🧰 4️⃣ Emergency Mini Tool (Unofficial Uses)
People sometimes use it to:
-
Bend small wires
-
Hold a thin nail or pin
-
Attach to zipper pulls
But these are creative uses — not what manufacturers officially designed it for.
🚫 What It’s NOT
-
Not a hidden measuring tool
-
Not a pressure point device
-
Not a medical feature
-
Not a “secret trick doctors don’t tell you”
A lot of viral posts exaggerate simple design features.
