TDS Forearm Blaster

The TDS Forearm Blaster is a specialized tool for training the forearms. I find that doing wrist curls on it induces a greater pump than I normally get via a dumbbell. The thicker grip (2" diameter) and the longer moment arm makes the movement challenging even at the top, whereas it would be easy with a dumbbell. As such, it alters the strength curve of a wrist curl in a similar way that a lever curl bar does for a barbell curl. I don't find it as useful for wrist extensions, however. (I treat this as a companion piece to Golden Grip's Forearm Finisher, which is specifically designed to train the forearm extensors.) I like to use disadvantaged leverage via a longer moment arm to help reduce the amount of weight I use while doing the exercise. Since the loading sleeve will be pointing straight down at the start of the movement, using less weight in the aforementioned way reduces the chance that the weights will slide down (or off) while doing the exercise. Given this, it is a shame that the default collar they provide is a cheap spring type that we've all grown to hate. Also, although there is a hex bolt at the end of the sleeve, I haven't had any issues with it coming loose during use.
