A system ( 18 ) for treating a work piece ( 12 ) with pressurized gas ( 16 ) from a gas source ( 14 ) includes a holder ( 49 ) for holding the work piece ( 12 ), a knife ( 52 A) that is in fluid communication with the gas source ( 14 ), and a support ( 54 A) that allows for movement of the knife ( 52 A). The knife ( 52 A) includes an outlet ( 64 ) for discharging the pressurized gas ( 16 ) towards the work piece ( 12 ) and impinging upon the work piece ( 12 ). The support ( 54 A) allows the knife ( 52 A) to move laterally relative to the work piece ( 12 ) while the knife ( 52 A) is directing the pressurized gas ( 16 ) toward the work piece ( 12 ) with the work piece ( 12 ) being maintained substantially stationary.
