1. A tool for manipulating a material, the tool comprising:
a body defining a chamber;
at least one source of a pressurised combustible, not classified as explosive, fuel and oxidant mixture, in fluid communication with the chamber via an injector device;
at least one nozzle, each nozzle having an inlet and an outlet, the inlet being in fluid communication with the chamber; and
at least one mechanism for igniting the pressurized combustible, not classified as explosive, fuel and oxidant mixture;
wherein, upon ignition of the pressurized combustible, not classified as explosive, fuel and oxidant mixture, a combustion jet is formed in the chamber which, in use, flows out of the tool through each nozzle outlet as a plurality of directed combustion jets directed towards, and into engagement with, a material to be manipulated.
