Choosing a size.
Most whips would love to have size 8 crackers, Smaller lighter whips prefer size 4 and heavy big whips size 16.
Size 8 is 1.5 mm or 0.059" in diameter, 8 yarns of Dupont Kevlar Yarn.
Size 4 is 1.01 mm or 0.043" in diameter, 4 yarns of Dupont Kevlar Yarn.
Size 16 is 2 mm or 0.079" in diameter, 16 yarns of Dupont Kevlar Yarn.
Yarn crackers are soft with very feathery feathers.
Typically these are made 8" overall with a 2" feather, though I can spin them custom for your order, just spec it out.
If you are not impressed with the crackers, send them back for a full refund.
These crackers are spun tightly, versus loose lay, this helps them tangle less.
These are mounted on a soda straw section to hold the eyes open for easy cracker installation.
Kevlar® does not melt; it decomposes at relatively high temperatures (800°F to 900°F [427°C to 482°C]
This makes them great for fire whip crackers.
Feathers are finished with a couple of very very small half hitches against the stem with a single yarn from each side of the feather to prevent unravelling, you can always add a bigger knot but these knots are as small as possible as they help keep the feather in place without creating a bump that bites or cuts during practice or performance. It also helps the feather have no point that breaks off as a big knot will create a point that breaks down the shaft of the cracker where eventually it breaks off.
