Zusammenfassung:	A downhole tool (1) for manipulating a target, includes a housing (2). The housing includes an inner surface (5) configured for mounting to a tubular carrier; and an outer surface (10). At least one chamber (20) is provided between the inner surface (5) and the outer surface (10) and contains at least one propellant source (22) and an ignition system. One or more outlets (12) lead from the chamber (20) to the outer surface (10), for combustion products from the at least one propellant source. The downhole tool may be employed for perforating and may be included in a hydraulic fracturing assembly. A method of hydraulic fracturing in a wellbore using the tool is provided.
