Two ropes. Two knots. One principle. Each side wraps twice and tucks back through itself — forming a barrel knot around the opposing rope. When you pull the ends, both barrels slide toward each other and jam. The harder the tension, the tighter the lock. There is no mechanism that can make it slip. The Double Fisherman's Knot has existed for centuries because physics hasn't changed. Elegant engineering. Zero moving parts.
