Uni Kuru Toga

It is an inevitable truth that Japan are pioneering the technology. Even in the pencils!

That's the reason why is not a big surprise to see innovations on a pencil which is an item not related to technology.

Uni Kuru Toga: A mechanical pencil keeps lead sharp all the time.

If you would like to keep enjoying newly shapened pencil all the time on a mechanical pencil this one is just for you.

There are also two other types of Kuru Toga called 'High Grade' (Metal Body) and 'Roulette' (Metal body and knurls at the holding part) are available.

Material quality of regular Kuru Toga is not satisfying enough but its wonderful lead rotation technology worths trying.

Well, how does the lead stays sharp all the time?

Kuru Toga Engine Lead Rotation Mechanism

As you can see clearly from transparent section each touch of lead to the paper rotates the lead by small angle and this rotation changes the contact point of lead resulting a triangular shape at the top and keeps it sharp all the time.
So, this technology prevents breaks and you can use the same lead for much longer time.

Only negative points about this pen are unsatisfying material quality and its intention to slip from hands after a short period of usage even there is a wave shape at the grip.

Pros:

+ Always sharp lead
+ Able to write with same lead much longer

Cons:

- Low material quality
- Intension to slip from hand
