The lumber crayon is just a thick hard crayon. Its advantage is that it marks easily on rough surfaces and makes big visible marks. It is commonly called a "keel", which appears to be an old Scottish word refering to:
“A variety of red ochreous iron-ore used for marking sheep, stone, timber, etc.; ruddle. Also, the red mark made with this on sheep, etc.” - source Oxford English Dictionary
They are now yellow or blue. The reason being that red (made from the above mentioned iron oxide) leaves a more permanent stain.

Probably from Scotland, where "keelivine" is still a country dialect word for an ordinary lead pencil.
