Sharpener ... Adjustable Lead Function

We found a very interesting sharpener last Friday (March 11, 2011) at Changi Airport T3 Fairprice supermarket.

This plastic sharpener has a lead adjustment knob which allow the user to decide how sharp he wanted the pencil.

It has five level of sharpest with one as the sharpest.

The picture above show sharpest level five, three and one.

This is a cheap and good accessories for the Singaproe urban sketchers and pencil users like us.
