The first one is more practical and traditional, but I can see the potential of the second one (are you looking for karambits?).

Karambits are more effective than other knives at cutting mainly because of biomechanics. This advantage would be lost with grav dust bracelets because your body wouldn't be holding the weapon. They also would do little damage in comparison to melee weapons due to the lack of mass in melee form, and would miss out on the speed of bullets and the versatility of unprocessed dust..

They also wouldn't work as effective climbing tools (if you were considering that as a possible function to increase mobility) because of their grip and inability to secure themselves into surfaces. (See ice climbing picks.)
