Word Definitions
chimwango: Hoe that has been worn down by use.
ndima: Portion of field allotted to one person or group of persons for weeding.
Translation
A borrowed old hoe does not get much weeding done.
Application
One should always remember that holding something in trust or being in possession of something borrowed does not translate to ownership. You therefore cannot safely rely on such things.
