There is something interesting I've noticed about weapons forms and training in Choy Li Fut over the years. It has nothing to do with uniqueness or special techniques based on weapon attributes or pairing, and it's not something you see in every weapon form. In fact, there are really just a handful of times you'll find these techniques at all, but a to me they're a real testament to the creator of the form's foresight and engineering.
The first thing I want to point out is context for the weapon, some weapons were used specifically on the battlefield and didn't need versatility as much as development of basics and repetition of common and practical combinations, like a long handled broadsword or a halberd. Then there's the interesting and unique weapons that also add flash and performance value through weapon spinning and even acting. For this, however, I want to look at the common day implements that could be weaponized in a moments notice for everyday self defense (even though most are not as everyday common as they once were). Weapons like cane, shoulder pole, flute and fan, or farming implements like hoe, rake, spade, branch cutting knife, and so on.
