{"title":"Liner Lock Knife","description":"\u003cp dir=\"ltr\"\u003e\u003cspan\u003eA liner lock knife is a folding knife held open by one of its own internal liners. When the blade swings open, a sprung section of steel or titanium liner snaps inward behind the blade's tang and wedges it in place. To close it, you push that liner aside with your thumb.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cspan\u003eThat design is why liner locks became the standard for one-handed folders: you can open and close them with the same hand, without shifting your grip.
