I use a plain old sheet metal hand nibbler.  Much cleaner and doesn't 
require dressing of the edges.   One usually can find them for USD$10 or 
less--all seem to come from Taiwan.  I've got one with the anvil 
modified to allow for notching of "dragon's teeth" when joining two bits 
of sheet metal.

My HP Scanner uses a C5/C6 connection, but a much smaller thin client 
uses the C7/C8--although later versions of that piece of equipment use 
C13/C14--I suppose that the maker (Neoware) received too much flack on 
their choice of receptacle.

The 2.5A rating on the C5...C8 connectors had me wondering if the UK 
versions have fused mains plugs--and if it's still customary to use the 
ubiquitous 13A fuses in those...
