Ah those Tourists ...
They always come along with their home appliances with out thinking wall plugs EU compatibility.
Especially local computers repairs stores, now owning last amount of BS1363 UK power plugs (NEW) because the customer replaced the cable by getting THE compatible version.
Few months ago I thought the possibility of using the large brass (Earth) pin in to another project, last day I asked few friends of my about
free of charge stock of such BS1363 and I got plenty.
One of them this is open-type and you may replace the cable, I will name this as golden standard and I will keep it as is.
The many... will be driven to grinding wheel, the plastic near to ground pin this get partially removed, plastic gets warm due friction and the pin can be then extracted.
Here are few pictures for you to see
My project of how to reuse such brass pins this is another story, for a later time.
