I must admit that I don't like it much either lol. But I still have never used anything else in the TM. Although I would never try using anything else throught the hole in the lid when the blades are running.
I dislike the TM spatula as well, at first I thought it was because I am left handed, now I use a Tupperware one that i had for awhile and not a nick on it, I bought a new TM one and it had cuts in it the first time I used it.
