I've only had this a few days and just tried it. So far this is not the best start. Revain's information states that ZokMok is an American company, but the packaging says it's made in China. On first use I noticed that it takes a long time to remove this amount of material and I have a few wavy lines and burn marks. Luckily it was a piece of white oak. If I decide to try this again I will update the review. It's very possible that I'm doing something wrong.
