Well no, the text for Forearm Snap Blades states that it's an external version of Spurs. Spurs are Unarmed Combat, but Forearm Snap Blades are listed as Blades. Odd.
Spurs use the Blades skill, not Unarmed. "Cyber-Implant Blades" is even listed as an available specialization for Blades.
Off the top of my head, only shock hands use Unarmed.
EDIT: Here we go.
Augmentation, page 169, lists all the different cyber-weapons by what skill they use. Ironically (and hopefully it will be errata'd away), it lists shock hands under Blades. At any rate, it does list all the
other weapons and what skill they use (Exotic Melee Weapons for the fangs and horns, that sort of thing).
It would be a totally understandable house rule (to me, at least), to change cyber spurs, hand razors, etc, over to Unarmed Combat. The direct neural interface brought about by paying Essence for the blade makes it feel like a part of the user's arm/hand and allows him to blah blah blah use the regular Unarmed Combat skill with it. I can see it making sense either way, and lumping it into Unarmed kind of helps the sammie that wants to be able to hit hard
and stab with an implanted weapon, without also being an expert fencer.
