I understand that it's important to keep my longest line of credit open, which is about 5 years. However, I really don't like using that credit card for logistical reasons (out of state bank, etc.) I use other credit cards regularly for all my expenses. My credit score seems good. Looking at my credit report with Experian, it looks like the oldest card has lots of "paid ontime" records, although the last time I used it was 2013.
I'm wondering if I can just cut up the card and keep the account open? Or is there some reason I need to use all of my cards to keep building credit.
