If you stop and think about it, it’s almost impossible to use an entire pencil because after repeated sharpening sessions you eventually end up with a tiny unusable stub. What a ripoff. There’s a solution to that problem, though. A clever new sharpener with multiple blades that lets you stack a stub onto a brand new pencil and keep using it until it’s completely gone.
Japan-based Nakajima Jukyudo’s Tsunago has three different holes and blades instead of just one. The first is used to sharpen a pencil like normal, but the second bores a hole in the bottom of a short stub while the third creates a plug on the tip of a brand new pencil allowing the two to be connected with a perfectly-sized interlocking joint.
The final step is to use a little bit of wood glue to permanently bond the two pencils together. Once dry, it can be sharpened again letting you reclaim the last few inches of a pencil you thought was destined for the rubbish bin. Brilliant. Available soon in Japan for about around the $9.50 mark, the Tsunago sharpener is one of those products that might eventually pay for itself if pencils are part of your daily routine.
