Not wood, probably plastic scales.

shooter's description fits what may have happened here.
Due to the stiffness of the pin, as I recall, I struggled to close the blade and unintentionally gave the scales a squeeze. It's quite possibly the cause.

I've got to say, some of the tips given are very welcome.
Loving the floss.

As it stands the WD-40 seems to be holding up well and doing the trick.

Many thanks to all. Regards,
