As others have stated, this is a tom thumb. It just has copper rollers/inlays and slightly swept back shanks. This is not a bad bit, it isn't as gentle as many people believe however. When you pull on the shanks, the joint nutcrackers up and can put pressure on the palate of the horse as well as pinching the bars.
Honestly I don't like these much either. I feel like there are many other hundreds of bits out there that are more clear when you signal (your cue can get lost in that palate pressure) and less harsh. If you want to stick to something jointed, I'd recommend getting something with two joints in the middle. My favorite (and my horse's favorites so far) is a small copper roller in the middle of two joints. I think its commonly called a "berry" or something similar. I have one gelding that does well in a french link also. I have several variations on that type of bit.
The shanks being swept back (rather than straight in line with the purchase) means that its a little less harsh as it gives the horse some warning that pressure is coming before it actually comes. It gives them a chance to react appropriately to your cues without being surprised and scared by them.
I agree with smrobs also however. Don't feel like you have to change. Any bit is only as soft as the rider's hands. That applies from the mildest snaffle to the most severe correction bit.
