expressions similar to "sword without a hilt"?

Anyone know any (semi)common expressions that mean the same thing (i.e there's no safe way to wield something)?

I'm writing a white paper and I don't particularly want to quote ASOIAF but it fits perfectly with my point.

Double edged sword

"something that has or can have both favorable and unfavorable consequences"

 

 

Having a "tiger by the tail" is sort of a similar but not identical concept.

DoovyB - What is a white paper Phone Post 3.0

Basically just a paper to help someone understand a situation better. Discusses the context, the problems, and proposes solutions. And it will probably never actually get read.
