African gray biting nails help

[Ianb]

He has lots of toys in a nice big cage
He is a very confident bird
He is hand reared
He's 4 years old Iv only had him about 8 week his nails were short when I got him
They are only about 1-2 mm long so when he comes out he hasn't got very good grip when he's out on my arm
Any help and advice will be appreciate
