Correct to call 'em DIKES?

[Rob & Heather Williams]

Dilemma:

(This is embarrassing) After lunch today a local all-female
rock band of a particular sexual orientation (TIN LIZZIE)
brought one of their analog synths (Arp Odyssey) into my
shop to have an XLR connector installed.  While doing the
mod, I got frustrated with a particular tool of mine that
had become dull with use and tossed them over to my partner
across the bench with the comment, "Would you get rid of
these DIKES!" (diagonal cutters).  I got some unusual stares
and it never dawned on me till these two were way out in the
parking lot what I had just done.  My partner Rod could
hardly keep from busting a gut over it.

Question:

Is it politically correct to call diagonal cutters "DIKES"
anymore?  I've been doing it for years, but if it's going to
lose me some business I better start changing my ways.
