Laptop charger adapter tips .. some advice required please

WLM21

My son has just stood on the the charger cable and has bent the adapter tip.

I initially thought I would have to buy a whole new charger, but now see that he has a universal charger, with gable, at the end of which is a small double ended connector which I now know (5 minutes ago) to be called an adapter tip.

Doing a quick look, these seem only to be sold as sets of 6 or 7.

I only need one, so why would I need to buy a whole set, after all ..Why waste money ?

I'll do a Google search to see which one fits the laptop, which is a Toshiba PSLD8E 00D008EN model.

thanks !
