A device for clamping and severing a compressible structure includes a clamp assembly and a cutting assembly. The clamp assembly has first second identical clamps coupled together to define a gap therebetween with posts spanning the gap. Each clamp has a pair of arms hingedly coupled to one another at first ends thereof and lockable to one another at second ends thereof. The clamp assembly defines an open position when the second ends of the arms are separated from one another and a clamped position when the second ends of the arms are locked to one another. The cutting assembly supports the clamp assembly in its open position and places the clamp assembly in its clamped position. The cutting assembly includes a convexly-curved cutting blade that passes through the clamp assembly's gap when the clamp assembly is in its closed position to cut through the posts spanning the gap.
