Blendkörper 1H (English name dazzling body) in short BK-1H is a smoke grenade made in Germany. The grenade consisted of titanium tetrachloride and a glass casing which protected the contents. The grenade works like a normal smoke grenade only that there is no clip pin so the grenade was enough to throw at once. After throwing and throwing the grenade on hard surfaces it crashed and released titanium tetrachloride which started to turn into a white cloud. Translated with www.DeepL.com/Translator
