Narrative:

During the evening of the event on an overnight; I received a call from my first officer stating he had received a call from the first officer to whom we xferred the aircraft. My first officer was advised tools had been discovered in the wheelwell during preflight. I had noted maintenance had been performed on a previous day and the aircraft had been flown by a crew prior to us. I assume we were the second crew to fly the aircraft with the tools in the wheelwell. The tools obviously were located in such a position not to be a problem during normal operations. As of this writing; I do not know the exact location of the tools; but suspect they were not in a location easily seen while performing a preflight. Maintenance should not have left the tools; but I did suggest to my first officer that using a flashlight; day or night; is good idea while checking the wheelwell. In addition to 'extra parts;' fluid leaks are easier to see.
