1.5" framing chisel (in the toolbox now)
Slick (in the toolbox now)
Corner chisel (in the tool box now)
Mafell mortiser (I had a makita - liked it and it offered options for unique applications and for smaller mortises - bit the Mafell can't be beat for fast, accurate mortises in a production setting)
Or
Mint condition Miller Falls with bits - this would be sweet
