confiscated by staff. ♪ homemade weapons the inmates have made from bed springs or melted down plastic. they're truly ingenious, but they're deadly as well. >> at california's san quentin state prison, we saw how sophisticated some inmate weaponry can be. this homemade pistol is known as a zip gun. >> this portion is filled with ground up matchheads. the two holes here, inmates insert a wick. the inmate takes a plunger, pokes shrapnel in the open end, pieces of metal, ground up zippers. when the target walks by the cell, officer or inmate, the inmate lights this, when it goes down, strikes the match heads, basically act like a firecracker and shoots the shrapnel out. >> the majority of inmate manufactured weapons or shanks

are designed for slashing or stabbing. the ease with which lethal weapons are made is shocking. this san quentin inmate who goes by the name speedy agreed to show correctional staff and lockup cameras just how simple it can be. he starts by using a roll of toilet paper as a crude forge to melt plastic coffee cup lids. >> i'm making a weapon right now. melting this plastic down into a shape. what i'm doing is trying to get a wad of it to where i can -- i have something to work with. you know what i mean? what i'm doing now is molding. this is like playing with clay. what i'm doing is -- is -- i got to get it all to this way like this. if i get it like this -- >> i think it amazes me how fast it can be made.

these surprise raids are usually successful in finding weapons. they present a unique challenge for lockup crews. >> it is action. it's real action. the only thing that you have to be careful of, you don't want to piss off the cell block. you run the risk of alienating the very guys you're trying to extract stories and cooperation from. so, we always hope that if there is going to be a raid, that it's towards the end of our tour at the prison. >> but tv crew concerns are the last thing on the minds of these officers. what they uncover can be the difference between life and death. >> it's an old joint. you can hide stuff anywhere. like at the i-beams under here. it's a beam, the best place. somebody walking to the chow hall. a lot of guys know where it is, but they won't tell because they don't want to get killed or hurt

for ratting. >> a hart time later, officer hamilton and his partner, officer mcgee, make a hit. >> i found two razors that were removed. blades were removed from the disposable razors. these can be melted into a toothbrush handle, real good slashing instruments. those are solid, very sharp razors right there. looks like my partner has found another one. the inmates who make these weapons often claim they're only for self-defense. but actions usually bear a different reality. >> take this, roll up a bunch of newspapers, even thicker than this, you have a good spear. we had a good sergeant killed here about 15 years with a spear made out of that stuff, a good, sharp point put on it. >> next, on "lockup raw" -- >> i was not exposed. >> one prisoner's attempt to
