A rotary knife includes a handle, a rotatable annular blade, and a blade carrier assembly. The blade carrier assembly includes an expandable blade housing operably coupled to the handle and configured to removably support the blade. The blade housing is movable relative to the handle between a blade-securing condition, in which the blade housing securely supports the blade for rotational operation, and a relatively expanded blade-releasing condition, in which the blade housing permits removal and installation of the blade relative to the blade housing. The carrier assembly includes a lever mechanism shiftably mounted relative to the handle and configured when shifted to expand the blade housing from the blade-securing condition to the blade-releasing condition. |
