It’s rare to see kung fu weapons like the tiger fork (or the kung fu trident) used in sparring. In general chinese polearms are mostly seen used in impressive wuxia fightscenes and taolu performances.
If you wanna see weapons like this used in sparring, then be sure to check out the Weapon Sparring playlist on my Youtube channel. Here’s a trident vs pudao (also known as the horse cutter) sparring video.
Note the use of wooden weapons and protective gear.
