在攀登过程中，绳结打法的对错和速度有时关乎性命，因此熟悉各种绳结的打法与其功能是极其重要的。绳结技术的掌握来自不断的练习，体会。初时可按图依样，然后离开书练习，甚至单手打出。每一个步骤都要非常正确，毫不含糊。要做到在黑暗中或其他各种条件下能自如打结，同时也应知道如何解开结，因为在许多危险时刻，不会解开结比不会打结更糟糕。所有的绳结在完成后都需收紧才能使用，同时绳端至少预留5厘米，以免意外松脱。
Origin: Dan Lehman described a variation on the Highwayman's Hitch at the end of his entry on March 6, 2004 in Google Groups rec.crafts.knots but he gave it no name. Roo replied, created drawings, named it the Tumble Hitch, and now shows it on his website Notable Knots. This is now the accepted name for Lehman's idea. Like a Slipped Buntline, it is an excellent quick-release hitch that holds a load until released by a pull on the free tail.
Quick Release Hitches: Many quick-release hitches have been described. The Highwayman's the Siberian (Evenk) and the Mooring are also described here. Of the four, the Tumble Hitch may be the most secure.
Real Danger: Quick release hitches share a major fault: entanglement of the free tail with the moving load can trigger abrupt release. A climber, frightened by a sudden slip or jerk, might grab at the adjacent line and trigger a fatal fall. Quick release knots should not be used for retrieving a climbing rope because there are recommended alternatives: 1, 2, 3, 4.
Other Uses: The Tumble Hitch is suitable for temporary, supervised use to hold non-critical loads, e.g., while boarding a kayak. Or, a dinghy may be temporarily secured alongside a high dock. The Tumble Hitch can be used to lower several loads of provisions into the dinghy. Then, when the owner has climbed down the ladder and is safely aboard, the tail of the dinghy painter can be pulled to retrieve it.
Advantages: The Tumble Hitch is stable and jam-proof even with heavy loads. The design of the hitch transfers the load first to an intermediate bight and then to the final locking bight. This limits the load on the locking bight and avoids jamming.
Longer use: To use the Tumble Hitch for longer periods, the final bight can be lengthened and tied off as an overhand knot around the standing end. The jam-proof benefits are retained and the overhand knot can be untied when the quick-release feature is required.
