Knife/Tool Sharpener (DA11)

Perhaps a long shot but does anyone have a knife/tool sharpener for our two Repair Cafés in Gravesend and Vigo.
We offer a free service to the public sharpening items like garden shears and secateurs as well as all manner of tools etc etc.
We need another one as we have two Repair Cafés and the service is popular.
The photograph is only a guide to what we would like to obtain if possible.

Thank You!
