The tashi gida or "tiger spear" was a large hunting spear in use by the Qing dynasty Tiger spear division. It was called hǔqiāng (虎槍) in Chinese.
It appears in the 1766 Huángcháo lǐqì túshì (皇朝禮器圖式) or "Illustrated Regulations of the Ceremonial Paraphernalia of the Dynasty" which in turn was based on a 1759 manuscript. See below the original page and my translations:
"According to the design of the 14th year of Qianlong.
Regulations of the dynasty; Tiger Spear Division's Tiger Spear: Spearhead made of forged steel. Overall 8 chi 3 cun long. Spearhead is 9 cun long, with triangular tip and center ridge. Shaft is 7 chi 4 cun long, made of white waxwood. At the top of the shaft are tied two transverse pieces of deer antler, 1 cun long. There is a horn ferrule at the end of the shaft. The spearhead is covered with a leather bag, wrapped with birch bark. It is carried by tying it to a leather belt."
