The Perrin PPT folder knife is a special edition with a black TiCN coating. It was designed by Fred Perrin, Philippe Perotti, and Sacha Thiel. The knife has a similar shape and feel to other Perrin designs. The lock mechanism combines features from Michael Walker's LinerLock® and Chris Reeves' Reeve Integral Lock, resulting in a frame-lock design with a black G-10 scale overlay that resembles a LinerLock. The scales are milled with corrugated creases to provide a secure and comfortable grip. The blade is made of CPM-S30V steel and has a modified-Wharncliffe profile with a finger choil and spine jimping. It also features a tapered spine-swedge. The knife comes with a reversible deep-carry pocket clip and a handle lanyard, allowing for various attachment options.
