Safety fuse

A black powder-cored initiating cord burning at approximately 8-10 mm/s. Used for controlled delay ignition; forensic signature is black powder residue at the termination point. Distinguished from detonating cord (PETN core) by its slower burn rate and deflagrating rather than detonating behaviour.
