The flexor tendons are smooth, flexible, thick strings which bend your fingers - they look a bit like clothesline rope. They work like a bicycle brake cable to bend your fingers, sliding in and out of the finger as it straightens and bends. If a flexor tendon is cut in half, the end connected to the muscle is often pulled back into the palm - no way to heal on its own. This is a very precision mechanism, and it doesn't take much to gum up the works. Even a cut only part way into the tendon can be a big problem.
