it's no mystery that japanese mechanical
pencils are a cut above the rest with
innovative features that enhance the
writing experience
but are some of these details over the
top
we'll talk about seven mechanical
pencils with remarkable engineering so
you can decide for yourself

let's get started
sliding guide sleeve
zebra delguard
any mechanical pencil user knows the
frustration of easily breaking lead
the zebra delguard combats this problem
with a two-part lead protection system
a spring in the pencil barrel lets lead
slide back into the pencil if it detects
too much vertical pressure
and another spring extends a metal
sleeve to reinforce the lead if too much
sideways pressure is placed on it
with this pencil riding is less
frustrating
and you save more lead in the long run
auto extending eraser
zebra delguard type er
the type er takes the delguard up a
notch
in addition to the sliding guide sleeve
it features an eraser that extends
automatically whenever you turn the
pencil upside down
the eraser locks into place and stays
put while you use it
then drops right back inside when you
flip the pencil over again
lead clutch
platinum olenu
most mechanical pencils can only clutch
the lead core until the last 10
millimeters after that the lead becomes
unstable and falls out rendering it
unusable
the olenu can clutch a lead core until
the very last 0.5 millimeters a 95
reduction in waste
aside from its lead clutch mechanism the
olenu also saves lead from braking
it has an internal spring that absorbs
shock during writing and a sliding metal
sleeve in the pencil tip that moves with
the lead to give it extra support

rotating lead
uni kuru toga
if you use mechanical pencils you know
the lead tip wears down unevenly as you
write causing a slanted edge and uneven
lines
eventually your line can become thick
and smudgy
yuni's kuru toga solves this issue with
a core rotation mechanism
using three gears the pencil features a
spring-loaded clutch that rotates the
lead slightly each time you lift the
pencil
this makes sure the lead wears down
uniformly and stays sharp
while the rotating may take time to get
used to and isn't suited for cursive
is the perfect pencil if you prefer even
lines for math sketching and more

shaker mechanism
tombow monograph shaker
with the award-winning tombow monograph
shaker you don't need to let go and
re-grip every time you want to extend
the lead
just shake the pencil up and down
you can also push the side clip for a
more conventional approach
to lock the shaker mechanism when not
using the pencil push the clip upwards
when it's locked you don't have to worry
about accidentally extending the lead in
your pocket or pencil case
tiniest tip
pentel orenz
the o-rens offers the smallest lead size
on the market its minuscule 0.2
millimeter tip size produces amazingly
thin lines
because the lead is so fine the pencil
features a long sliding ledge sleeve
that shields the entire length of the
lead protecting it from breaking
as you write the lead sleeve gently
touches the paper and retreats back into
the tip of the pencil as the lead is
worn down
since the edge of the lead sleeve is
rounded it won't scratch or catch on the
paper
auto extending lead
pentel oren's narrow
the oren's narrow takes the orens a step
further with its automatic lead
advancement system
each time you lift the pencil from the
page the lead extends
once you begin writing you won't have to
click the top button again until the
lead runs out
its special resin metal body also feels
sturdy in the hand with a well-balanced
weight that makes riding more
comfortable
do you think these features are
excessive or should they be standard for
all mechanical pencils
