I just bought the chisel spring tool. A few days ago I tried to remove two rivets when replacing a car door handle. I used a small angle grinder, drill and other tools to try and remove the rivets. Bad idea. Took too long and did more harm than good. I was looking for rivet removal tools and came across spring tools. I can only say wow! It only took me 8 seconds to remove the rivet. This was the first time I used the tool. Not only did it outperform every other tool I've used, it blew me away. Simple and uncomplicated tool purchase. It's worth its weight in gold. Very happy with the results, I decided to buy all the tools Spring Tools has to offer.
