A cutoff tool for severing a neck of a difficult-handling fluid material (a fluid material which is highly viscous, highly adhering, highly cohering, and/or shear thickening) includes a rotating whip, for example a string or a wire. The whip may be rotated at a sufficiently high rate, for example by a motor, so as to prevent adherence of the fluid material to the whip, for example by use of centrifugal forces to fling fluid material off of the whip. A system for filling containers includes a cutoff tool operatively coupled with a filling nozzle and a container clamp. A method of filling a container may include clamping the container, inserting a filling nozzle into the container, dispensing fluid material into the container, withdrawing the filling nozzle from the container during and/or after the filling, drawing back fluid material through the filling nozzle so as to thin a neck of fluid material between the filling nozzle and the filled container, and severing the neck, for example by using a cutoff tool.

1. A system for at least partially filling a container with a fluid material, comprising: a clamp operationally configured to hold the container; a nozzle operatively coupled to a supply of the fluid material, the nozzle operationally configured to dispense the fluid material into the container; and the cutoff device operationally configured to cut a neck of the fluid material between the nozzle and the fluid material in the container; wherein the cutoff device includes: a cutting whip which rotates at at least 8000 rpm; and a motor operatively coupled to the whip to rotate the whip. 2. The device of claim 1, wherein the whip rotates at at least 10,000 rpm. 3. The device of claim 1, wherein the whip rotates at at least 15,000 rpm. 4. The device of claim 1, wherein the whip rotates at at least 20,000 rpm. 5. The device of claim 1, wherein the whip rotates at at least 22,000 rpm. 6. The device of claim 1, wherein the whip includes a string of polymer material. 7. The device of claim 6, wherein the string of polymer material is a length of fishing line. 8. The device of claim 1, wherein the whip has a diameter of 0.028 to 0.030 inches. 9. The device of claim 1, wherein the motor is an air motor. 10. The system of claim 1, wherein the cutoff device is horizontally movable relative to the nozzle and/or the clamp. 11. The system of claim 1, wherein the nozzle is vertically movable relative to the damp. 12. The system of claim 1, further comprising a metering pump operatively coupled to the nozzle and the supply of fluid material. 13. A method utilizing the system of claim 1, for at least partially filling a container with a fluid material, the method comprising: securing the container in the clamp; dispensing the fluid material into the container through the nozzle; and cutting the neck of the fluid material between the nozzle and the fluid material in the container. 14. The method of claim 13, wherein the dispensing includes inserting the nozzle into the container, introducing the fluid material into the container, and withdrawing the nozzle from the container during and/or after the introducing of the fluid material. 15. The method of claim 13, further comprising, between the dispensing and the cutting, thinning the neck by drawing back some of the fluid material through the nozzle. 16. The method of claim 13, wherein the fluid material is a shear thickening fluid material.
