The blasting safety fuse, employed to fire an explosive from a distance or after a delay, is a hollow cord filled with a mixture resembling black powder and designed to propagate burning at a slow and steady rate. The far end of the fuse is usually embedded in the explosive charge.

A model rocket fuse is typically a cord that can range in length from a couple of inches to a few meters. The fuse when lit offers a slow and controlled burn to ignite the engine. And if using a fuse in a model rocket it needs to reach the propellant inside of the engine. In this post, we will go through what does a model rocket fuse does.

Igniter cord is designed for ignition of propellants and explosives (demolation). It is not ment to be lit by hand (very hot flame), and if there is any sheeting, it will burn several inches or more a second If you use this as a fuse, the model rocket can (and if you chose fast speed; will) take off the second you put the match to the cord.
