All of the equipment looks very important in the sport of fencing but I am wondering what is the most important piece when you are just starting out. I have received a few lessons from my local studio and I was able to rent the fencing gear but if I wish to continue in the sport renting can get very expensive. If I were to just buy one or two key pieces of equipment what should I buy? I do not want to make a major investment in case I do not care to pursue it but a couple of pieces would be fun to look into.
