Hi All,
I have a set of cheap crapy B&Q (spits over left shoulder) router bits which
I use for rough work (the good bits I save for the final cut); they seem to
keep an edge for (roughly) the first 3.2 seconds of use (well, maybe a
little longer). Can anyone offer advice on sharpening these bits? When I
bought them I considered them to be disposable, so any extension of life
will be a bonus.

TIA.
