Tombow Olno Body Knock Mechanical Pencil
The Tombow Olno is an affordable mechanical pencil with one very cool trick: you extend the lead by bending the pencil at the middle. This mechanism is known as a “body knock” and it’s quite cool because it allows you to extent the lead without having to shift your grip.
The Olno is notable because of its large, ergonomic grip and because it’s one of the most affordable body knock pencils ever sold, as a retail price of about $10.
