Dissection Dilemma

YOU HAVE taken up the hobby of jewelry making and you want to join the four pieces of silver chain shown at the left to form the circular bracelet shown at the right. Since it takes a bit of doing to cut open a link and weld it together again, you naturally want to cut as few links as possible. 
What is the minimum number of links you must cut to do the job? 

The Answer:

It is only necessary to cut the three links of one piece. They can then be used to join the remaining three pieces into the circular bracelet.
