I do know stationery nerds but I am not one... (Do you sense another BUT coming?) but I've found a pencil I really like amongst pencil crayons my kids used. It's a Rowney Black Beauty 874A. Like this but LIGHT blue, chunkier and a bit chewed. https://brandnamepencils.com/product/black-beauty-874. It's REALLY Black.

@woo Have you considered getting it professionally sharpened? http://artisanalpencilsharpening.com/
@mavit He moved to engineering clutch pencils, to protect his point :-)
@mavit I haven't. My Dad was a draughtsman, so I had coaching when I was young and a pen-knife! I skip the final sharpening with glass-paper now. :-)
