Told you so!
In my dictionary the opposite of decent is indecent, perhaps the problem was the use of the word decent?
In any case the plastic tool (which came free with an old phone wiring extension kit I think) is 'adequate'.
For a single job I suppose it is.
You would never get me using a screw driver / table knife / anything else not designed for the purpose.
Must say I get some satisfaction hearing/feeling my krone tool punch down and snip the ends of the pair. I'm confident that ain't coming out any time soon.
Manipulating a flat head screwdriver to push the cable deep enough while trying not to damage the IDC teeth just doesn't do it for me.
