During the Movie you see 3 different Generations of the Merchant Family pay attention to how Pinhead kills the second generation male in the 1990's (please give or take me a couple decades thats not important)he kills Merchant using a Chain with an opening blade at the end . 1st he fires the blade with the chain attached through merchants neck as it goes in merhcant grabs the chain that protrudes out in front of him.the blade goes all the way through his neck out the other side and then opens up,then pinhead uses his powers to bring the blade back which cuts merchants head off . but it doesn't cut his fingers off.and when you watch it it should clearly cut his fingers off. If you watch the part you will Notice what i mean.
