Pictured above are two pencil extenders (and a new pencil for comparison). They are devices that give a second career to pencils that might otherwise be approaching retirement. Pencils can last quite a while, so the ones that have been used until they turn into stubs are probably the really good ones – the ones we most often choose for our writing or drawing tasks. These extenders can allow a pencil to be used even when many sharpenings have made that pencil no longer comfortable or practical to be held in one’s hand.
Above are a No. 1098 N Koh-I-Noor, and a Cretacolor extender, with a new Cretacolor pencil for comparison.
I found them both at art stores. They are quite comfortable and simple to use. The pencil stub is placed in the opening, and a clamping ring moved to secure the pencil. With certain pencils being hard to replace or expensive (e.g. artist’s pencil crayons), one or two of these extenders could certainly be a good investment.
