I've managed to add modifications to other weapons like the staff, so it's not me being stupid. But i sthere any reason I can't add grips to my dagger?
Here are the grips I just made.

Here is the dagger.

It's a dual-blade dagger grip. It won't go into a single blade dagger obviously just as you can't use hafts on longswords.
On another note you get most dps out of +X% flanking damage. No sense in clowning around with +crit and stuff, you will be hitting stuff in the back anyway.
Oh okay, so I am stuck with a tier 1 dagger grip for this one. It would be nice if it said I had to use a "Balanced Dagger Grip" rather than just "Grip".
Never saw a dual-blade dagger, but my hunch is that its grip will say dual-blade grip or something along this. It's differentiated enough, just read the text.
