Pathfinder and Pathfinder CS files by Sybron Endo have a minimal taper, which assists greatly in negotiating calcified or otherwise difficult canals. These stainless steel files are packaged in impact-resistant, clear plastic boxes, in groups of six. These boxes even have stripes along the length, indicating 21mm, 25mm, and 30mm; this allows for easy size identification of its contents, without measuring files or even opening the box! Pathfinder CS has the additional strength of carbon steel in its makeup, allowing it to navigate the toughest canals faster and more efficiently.

In terms of sizes, the original Pathfinders are available in 21mm and 25 mm lengths. Pathfinder CS files are offered in 19mm, 21mm, and 25mm lengths, and are color coded on the handle between K1 (dark brown) and K2 (orange) options.
