Welcome to Kirin Academy!
Replacing the cracker (the lash) on your Kung Fu whip is a basic but essential skill. A fresh cracker ensures a massive sonic boom and smooth handling. In this tutorial, we will walk you through the step-by-step process of removing an old cracker and correctly tying new ones.
🛠️ Tools You Will Need
- A seam ripper or small knife (included with your Kirin Whip order)
- A pair of scissors and a ruler
- Your replacement cracker (Nylon Ribbon or Dyneema Rope)
Step 1: Removing the Old Cracker
After repeated striking, the knot on your old cracker becomes extremely tight and hard. Use your seam ripper or small knife to carefully loosen and cut the knot. Important: Be very careful not to scratch or damage the metal loop of the whip itself!
Step 2: How to Tie a Nylon Ribbon Cracker (Korean Silk)
The Nylon Ribbon is the standard choice for most whips. It creates the loudest sonic crack and offers superior control for flow arts and performance routines.
- Measure and Cut: Cut a piece of ribbon about 50 cm (20 inches) long.
- Find the Grain: Pull the threads on both ends. One end will unravel easily (fray), and the other won't. You must tie the unraveling end to the whip's head. (Trim the messy frayed part first).
- Thread the Ring: Fold the unraveling end in half and thread it through the whip's metal ring.
- Create the First Loop: Use your fingers to spread the ribbon loop open, pull the whip head through that loop, and pull it tight.
- Lock It In: Take the long tail end, flip it, and feed it through the new loop you just created. Pull both sides firmly to lock it in place. The more you crack the whip, the tighter this knot becomes!
- Final Length: Your final cracker should be about 30 to 40 cm (12-16 inches) long.
Step 3: How to Tie a Dyneema Rope Cracker (For Heavy Whips)
If you are using our Heavyweight Power Whips (like the 5kg beast), a nylon ribbon will snap in just a few strikes. You need the ultra-durable Dyneema rope.
- Thread the Ring: Thread one end of the Dyneema rope through the metal ring. (Dyneema has no grain, so either end works).
- Open the Rope: Twist the rope slightly to open a small gap in the braided fibers.
- Feed and Pull: Feed the long tail end through that gap and simply pull it tight. It won't come loose no matter how hard you crack it.
Pro Tip: While Dyneema is incredibly wear-resistant for heavy training, it is not as loud. For the best sonic crack and handling on standard whips, always stick with the Nylon Ribbon!
