Nail Grenade by the Jolly Roger
Effective fragmentation grenades can be made from a block of tnt or
other blasting explosive and nails.
Block of TNT or other blasting explosive
Non-electric (military or improvised) blasting cap
Tape, string, wire, or glue
1) If an explosive charge other than a standard TNT block is used, make a
hole in the center of the charge for inserting the blasting cap. TNT can
be drilled with relative safety. With plastic explosives, a hole can be
made by pressing a round stick into the center of the charge. The hole
should be deep enough that the blasting cap is totally within the
2) Tape, tie, or glue one or two rows of closely packed nails to the
sides of the explosive block. Nails should completely cover the four
surfaces of the block.
3) Place blasting cap on one end of the fuse cord and crimp with pliers.
NOTE: To find out how long the fuse cord should be, check the time it
takes a known length to burn. If 12 inches (30 cm) burns for 30 seconds,
a 10 second delay will require a 4 inch (10 cm) fuse.
4) Insert the blasting cap in the hole in the block of explosive. Tape or
tie fuse cord securly in place so that it will not fall out when the
grenade is thrown.
An effective directional anti-personnel mine can be made by placing nails
on only one side of the explosive block. For this case, an electric
blasting cap can be used.
