Honestly letting you use tricks across weapon types like that would probably lead to a lot of suspension of disbelief breaking things like Thread the Needle with a straight razor...
Oh, man. I can totally see that one
. You just swung on a guy using a straight razor, and at the and of the motion you've got your blade resting on the side of his neck and there is blood running down his chest. That dude is not moving one damn step until you let him (or he wins an opposed grapple check and ducks out without losing the rest of his blood supply).
10th level martial artist who knows his staves and chooses to use a straight razor = One Bad Muther.
or Hack! with a garrote or stuff like that.
Garrotes are usually part of grapple actions, while hack!
goes with standard attcks, so not much to combine there.
