I have a passive (non-powered) permanent magnet type demagnetizer  that 
has a rectangular hole for magnetizing, and a "D"  shaped hole for 
demagnetizing . It works well with screwdriver blades, and the hole is 
large enough for thin pliers or side cutters, but haven't had the 
oportunity to try those. The link below is for a similar, mine doesn't 
have the steps on the hole:
