I mostly use the square pins from SIL headers, bent into an appropriate shape. I use a pointed tip but I don't think it matters much, as long as it can transfer heat into the pin.

I most recently used this to repair a snapped headband on some sony headphones. I'd previously tried to superglue it, but the glue eventually came undone - but my "staples" are still going strong.
