What you get
Sharpen some pencils — and your engineering knowhow — with a pencil sharpener you built yourself! Follow step-by-step DIY instructions to construct the core, add the battery, and wire your mechanism up. Then learn about the invention of pencils, the evolution of sharpener design, and cool engineering features in your sharpener (like the limit switch, which lets the electric circuit know when your pencil is in the sharpener, causing it to automatically switch on)!

Reviews
really fun to make. works great!
My brilliant 10 yr old grandson LOVED this one. One of the legs did break and had to be glued, but no big deal. He is switching from Tinker to Eureka. Keep the great kits coming!
Love, love, love! My almost 12 year old had a blast putting this together and using at his desk! Such a great project!
