RETRACTABLE CLAWS

Retractable claws are implanted into the recipient’s hands. The claws are typically made of ceramic or carbon fiber compounds with durability and hardness rivalling steel. The claws also assist in climbing and may be used as a melee weapon. The recipient gains a +2 equipment bonus on Athletics checks to climb. If the recipient beats the DC of a Climb check by 5 or more, they are not considered flatfooted while climbing.

Attacks with retractable claws are considered unarmed strikes.  Any feat that modifies an unarmed strike modifies attacks with retractable claws. Retractable claws do an additional +1 damage per damage die, all damage is considered lethal, and have the operative special quality. Retractable claws are not subject to disarm attempts but may be sundered while extended. 

Retractable claws come in a couple variants.  Neutron dense (ND) retractable claws have been hardened by a process called neutron enrichment, a process where free neutrons are forced into the empty space between the atoms in a molecular lattice of heavy metal.  This make the material extremely heavy and dense.  ND retractable claws do an additional +3 damage per damage die, but the recipient receives a -2 penalty on To Hit rolls.

Molecular thin-blade (MTB) retractable claws appear translucent like glass and vibrating particles, allowing the dagger to slice through almost any substance.  MTB retractable claws have the penetrating weapon property. For additional information on the penetrating weapon property, see the "Equipment" section in Chapter 7 of the Starfinder Core Rulebook.
