Indeed it's weird.

I was thinking of a context as for example one saying to another "listen, because I have a weapon which injures, and because it injures it causes pain, beware".

Perhaps in that context one could say {rIQchoHmoHbogh nuH vaj 'oy'choHmoHbogh vIghajmo'}, in order to express that the "hurting" is the result of the "injuring" done by the weapon.

Of course, there wouldn't be any (considerable) difference in meaning if one just wrote {rIQchoHmoHbogh nuH 'ej 'oy'choHmoHbogh}, and of course one could avoid this altogether by rephrasing.

Anyway, I thing that meaning-wise perhaps it wouldn't be a problem writing {rIQchoHmoHbogh nuH vaj 'oy'choHmoHbogh vIghaj}; and perhaps in spoken Klingon, it would work even better by altering the tone of the voice while saying the {vaj 'oy'choHmoHbogh} part.

But I think that perhaps it would work better by placing the {'ej} before {vaj} because without it, it would be like writing {rIQchoHmoH 'oy'choHmoHbogh nuH} which would be strange.
