Includes some instructions for beginners. Whilst this is a great sharpener for all skill levels and interests it is in the price range of a beginner sharpener so I believe it would result in much more positive reviews if instructions were included. An explanation of what the numbers mean, what different pottery is used for. Tips on finding an edge to use and a suitable angle. The reason I believe this will lead to higher ratings on average is that people (including me) with no experience or instructions on how to sharpen try to use it incorrectly, get bad results and are tempted to leave bad feedback. Overall I gave 5 stars because it's a great product once you understand how to use it. I'm glad I started with the $20 Blade and not the $200 MicroTech.
