Battery cover tool for transistor portables

[Refugee]

This is an idea I came up with when a horrid plastic potato masher was going to be chucked out.
I never need to brake my finger nails ever again while changing batteries on transistor portables.

I play around a lot with mobile phones and one of the problems is how to open them without causing damage. I have seen tools on the net for about £6 +pp but they are not to hand when you need them, foresight and lazyness come to mind too.
I needed to change the batteries in our HTC one S's and a pizza cutter came to mind.
I had an old one with a nylon blade which I had used for folding corrugated plastic.
Superb, just the ticket, It can be rolled around the joint line and opens the phone like a can of sardines, well sort of......

It did indeed work like nylon with the little line of saw dust along the cut edge.

The tools are known as 'Spudgers' and widely used for removing plastic cases to gain access to such things as I-phones, I-pads, laptops to repair them or replace screens:

Maplin sell spudger kits too.

They abound on e-bay of course, and there are scores of videos on using spudgers in the repair of phones and laptops on youtube.

Some spudgers are metal but they don't have sharp edges, unlike screwdrivers which many are unwisely tempted to use.

I improvised by filing down a plastic toothbrush handle.
