You can fill a little bottle with tsubaki and put some splashes choji oil in it (more liquid and typical smell). Pure tsubaki (camelia) is very thick. A german manufactur offers a mixed camelia oil with some more liquidity (Dictum company). When using pure camellia oil, it tends to dry on the blade if you don't check on it for a while.
Btw tsubaki is the best choice for kitchen knifes. That oil is food safe. You can use it for your hair, lipps, and dry skin. Tsuruta san says tsubaki is salad oil.
