Fred,

This is not a problem with the powdered iron cores, but it is a problem with
ferrite cores - it is an abrasive material and when will have sharp edges,
just the nature of the beast - sort of like the fact that sissors are sharp
and often pointed.  It is a characteristic of the material and not a quality
consideration.

73,
Don W3FPR
