Anywhere in Wirral that could do that, all can find online is lawn-mowers on industrial estate in Prenton, bit out of way for me
Depending upon what knifes your sharpening, you may try a key cutter as they have grinding wheels. Failing that the Market could be a punt.
* In this day and age, you would probably be walking around with a lethal weapon (The knives).
If your asking "anywhere" on the Wirral, why say Prenton is out of the way?
The Lawn mower company is on the Durly industrial estate and with out transport its out the way.
