Ron Lake Folder: Compared to making a folder, building a fixed-blade knife is a walk in the park. Folders are the true test of a smith's skill as a machinist and designer. For over 30 years, Ron Lake has been one of the premier makers of folders. He developed the Inter-Frame concept: A steel frame surrounds the handle scales, enabling him to use relatively fragile materials like sheep horn without any fear of chipping. Lake knives also employ a Tail-Lock, a protruding lever at the rear end of the handle that locks the blade in place and then releases it. A great many Lake folders are fancy; all are tremendously strong, and the workmanship of them is unsurpassed.
