Trying to cut the carpet or fix it yourself is a very bad idea.
Carpets are woven from different materials and using different methods. You will not be able to repair it yourself, because the hand-made carpet is different from the factory one. My carpet is already quite old and it is very difficult to restore it to its original state, but I found a company that can help with this in a very short time.
I'm talking about
dazzlingcarpetrepairs.com.au. They are great at repairing carpets for a small price. I was very pleased with their renovation.
