Personally I have always preferred blades over unarmed, especially since you don't have to worry about the weird weapon foci/killing hands issue. Also, you can get some really nice AP by going with the claymore/nadochi out of R&G. Acc on it is alright (5), but the damage (STR+5), AP (-5), and reach (2) are awesome. Only thing is you can start will it in regular play (availability 14R), but you can start with a combat knife which has ridiculous stats, cheap, easy availability, and not even restriced. Unless you want to sack ~1 essence for 'ware to boost your unarmed damage, blades will out damage unarmed in this edition, and once you bind on as a foci, spirit armor doesn't apply either.
