Bits - Abstract Thursday AT136
These bits help me to take things to bits. This is (part of) my computer tool kit - this particular one is excellent, and I whole heartedly recommend it to anyone who actually needs to disassemble computers (or other technology) more than occasionally.
If you're interested you can find it on Amazon here.
I have it out because these picture things take up so much space, I need to expand my laptop - so additional 4TB drive going in after I finish typing this.
( I figured that I'd do this first - 'cos it might not work again afterwards :-P )
