Detonator crimping pliers, cap crimping pliers or detonator crimping tool is a common tool when working with explosives. The construction is very similar to the construction of any other multi-tool or pliers. The specific feature is the presence of one groove on each of the opposing jaws.
a small amount of a more powerful secondary explosive, directly in contact with the primary, and called "base" or "output" explosive, able to carry out the detonation through the casing of the detonator to the main explosive device to activate it. Explosives commonly used as primary in detonators include lead azide, lead styphnate, tetryl, and ...
The exploding-bridgewire detonator (EBW, also known as exploding wire detonator) is a type of detonator used to initiate the detonation reaction in explosive materials, similar to a blasting cap because it is fired using an electric current. EBWs use a different physical mechanism than blasting caps, using more electricity delivered much more ...
Setting off the NASA standard detonator, which itself activates other systems explosively. Triggering Pyrotechnic Circuit Interrupters, severing bundles of electrical cables. Triggering explosive valves to open/close pressurization lines or fuel lines. Triggering a pyrotechnic pin puller which opens a Marman clamp, separating two spacecraft.
EWM has found its most common use as a detonator, named the exploding-bridgewire detonator, for nuclear bombs. Bridgewire detonators are advantageous over chemical fuzes as the explosion is consistent and occurs only a few microseconds after the current is applied, with variation of only a few tens of nanoseconds from detonator to detonator.

(A) Slapper detonator's pellet or flyer impacts a wider area of surface on the explosive output charge, and even though energy is lost to the sides of the area impacted, a cone of explosive is efficiently compressed. (B) EBW detonators only initiate a single point, and energy is lost in all directions, making the energy transfer less efficient.
A shock tube detonator is a non-electric explosive fuze or initiator in the form of small-diameter hollow plastic tubing used to transport an initiating signal to an explosive by means of a shock wave (also known as a percussive wave) traveling the length of the tube. [1] Shock tube is used to convey a detonation signal to a detonator. Shock ...
Nonel shock tubes (pink, red, orange, yellow) with Orica surface delay connector (blue) in use. Nonel is a shock tube detonator designed to initiate explosions, generally for the purpose of demolition of buildings and for use in the blasting of rock in mines and quarries.
