An assembly tool for facilitating assembly of a surgical instrument includes a handle, a neck extending from the handle, and a portion of or an entire pivot pin engaged with the neck via a frangible connection. The pivot pin is engagable with the surgical instrument. The frangible connection is configured to break upon application of stress thereto above a threshold, thereby separating the pivot pin (or portion thereof) from the neck. A method of assembling using such an assembly tool includes positioning a component of a surgical instrument for receipt of a pivot pin, manipulating the assembly tool to operably engage the pivot pin with the component, and manipulating the assembly tool to apply stress to the frangible connection to break-off the pivot pin (or portion thereof) from the assembly tool along the frangible connection.
