Toko has a pocket style side + base tuner. I think it's .5 and 1 for base and 88/89 for sides.
I've got one of those. Only fits Toko files, not diamond stones or any other file type.
For the base, get one of these
Beast Base Bevel Guides
For sides, get something like:
SVST Pro-Edge Side Bevel Guides - Aluminum
That way you can use any file or stone
