The sledgehammer thing is a classic boxing exercise, earlier chopping would etc. hey if I remember it right even Rocky did it in the first or second Rockymovie All the best The predator
In the main, handspeed is a byproduct of good technique - if you want to improve your handspeed, improve your punching technique. Short duration isometrics will increase 'starting strength', plyometrics will help, complex training is very good for building 'explosive strength'. Both starting strength and explosive strangth can carry over to your punches, but as I mentioned above, this will only be the case if you technique is good. All of the physical attrributes in the world won't make you a fast and effective puncher without the technique to back it up.
technique,timing and the ability to be relaxed and loose when throwing punches you should always start off slow then graduallly increase speed for the sake of the above focus heavily on being light,springy,and snapping the punches - not pushing them also focus on reaching top velocity at the start of the punch- not gradually
Regular boxing training will allow you to develop your full hand speed potential. The question is how dedicated is your training? If you train with the same intensity as Manny Pacquiao you might get the same results.
also apart from technique, practice and mental focus as described above, some resistance excercises will improve handspeed and power one of the best i can think of would be to use slightly heavier gloves when doing bagwork and padwork, while simultaneously wearing a weighted vest too much extra weight on the hands though would be counterproductive a lot of speed comes from the speed of the torso twist and inertia which is wear the vest comes in handy if your technique is compromised and you feel you have to use too much muscular effort then that means your using too much weight also chopping with an axe is good, but it must not be too heavy, and it's a good idea to wear a vest for this too using heavier axes is no good - it's supposed to be an explosive yet relaxed effort and if your shoulders are supporting too much weight the technique is compromised
Hmmm I'm not sure if this would work, but try resistance bands too? If it helps sprinters and football players run faster. I don't see why it wouldn't help your hands get faster
resistance bands give constant tension which is the complete opposite of the mechanic of a punch it's a ballistic action not a pushing action baseball pitchers use slightly heavier balls in training (overload), but never more than 20% the original weight they also use lighter balls for underload training, which is why boxing with lighter gloves or punching without gloves is also important i don't see how you can punch properly with bands anyway
