For those who haven't seen it yet, Freud is making a wonderful blade set for making box joints on the table saw, the SBOX8 Box Joint Cutter Set. I picked up a set over the weekend and they are FANTASTIC! The teeth are designed for cutting end-grain cleanly and a simple swap of blade position changes from a 1/4" to 3/8" joint. They are shown on the new products part of the Freud web page, scroll down and you'll find it. They're not that expensive (about $80.00) considering how much better they are box joints than a traditional stacked dado.
