I bought some strings recently and they all came tied with a cable tie. Do you cut the cable tie carefully without cutting the string or do you just slide out the string under the cable tie? If I cut the cable tie carefully, the string gets tangled easily and I would spend almost 5 minutes to detangle it. If I slide the string under the cable tie, it takes a long time to open the string. What is the right way to open the packaged string?
