How durable is the finish? How long will the finish last?
This answer is a bit more complicated. Because the finish applied is a natural finish it reacts differently to the wood it is applied to, to the environment it is kept in, even to the person’s hand that uses it. Some woods (like Cherry and Olive) tend to absorb the waxes over time, giving the pen or pencil a more “satin” finish. Keeping the writing instrument in a cloth “environment” like a shirt pocket for long periods of time can tend to wear away the wax finish, how quickly depends on the cloth material. Because the finishing process embeds wax into the wood structure, the wood is still protected even though it may have taken on a more dull finish. Even the users body chemistry can have an affect on the pen or pencils finish. Skin acidity and/or oilyness varies from person to person and can have varying affects on the outer finish of your instrument.
