Now I don't know of every bit ever made, but there are good bits for beginner horses and there are good bits for beginner riders. Asking if a bit is too harsh is the same as saying this fork made me fat. Its not the bit its who's hands are using it and what horse are you putting it in. To train a colt with a spade bit would be way way way past harsh, does that make spade bits harsh? No. in the right hand and in the right horse a spade bit can work and not be harsh.
As to your question about tom thumb bits I agree with everyone else I real don't like the cheep tom thumb bits and I am working them out of my program.
