Why is Deng Feihu's slingshot tied vertically

Deng Feihu's slingshot is an old-fashioned slingshot with an old-fashioned tying method, where the leather strap has no taper and is tied up vertically. The tying method is due to Deng Feihu's personal habits, preferring to use this traditional tying method.

Deng Feihu's slingshot performance also benefits from this tying method. The old-fashioned tying method makes the slingshot more stable and enables better control of the direction and strength of the slingshot's launch, thus improving the accuracy of the shot.
