This tree folder has a 440C blade and an old style opening function. This is a 3 part knife, where part 3, the blade, sits inside part 2, which is the blade seat, and part 1, which is the frame. To open, fold down part 2, which then allows you to fold down part 3. After the blade, part 3, is folded out you fold up part 2 back into part 1, and the blade is ready to use. After practice you can do this quickly and effortlessly.
