I picked these up at one of Stockroom's woodworking seminars and I've been very happy with them. I mainly wanted the glue joint and drawer lock so haven't used the European lip yet (and honestly not quite sure how it works either).

The drawer lock and glue joints both take a little trial and error to setup but once done you can run a small reference piece through and set it aside as a quick setup guide for whenever you are using that thickness of wood in the future.

The tri-wing design seems very good. Quick, easy cuts without burning. I used these table mounted with a 2.5hp Triton router and it handled them with ease, I was very impressed too with the feed rate I could achieve, I attribute some of that the the 3rd knife in this design.

Haven't cut enough yet to comment on longevity of these bits but so far so good. Mine came with a wooden box too that's always a nice touch. (Posted on 8/21/10)
