The rotating mechanism...
The rotating mechanism works wonderfully and I won't use a regular non rotating
mechanism unless my Kuru Toga is not available. I have the 0.3mm and 0.5mm Kuru
Toga (0.7mm on order) and they are all the best mechanical pencils I have used.
I use the 0.3mm for fine work and the 0.5mm for regular work although I find the
0.5mm a touch fine (my son thinks the Kuru Toga 0.5mm is perfect).
The 0.5mm lead has about 3 times the volume of material than a 0.3mm lead and
they last quite awhile before having to advance the lead. The Kuru Toga advances
the lead a relatively short amount compared to some other mechanical pencils and
that helps reduces breakage. The only time they break is when I don't let the
lead wear right down before advancing.
Once the lead pushes past the advancing/rotating mechanism it is best to advance
a new lead and throw away the rather long bit you just pushed through. I tried
using up the non rotating lead by pushing it through from behind one click at a
time but small pieces of the new lead kept breaking off inside and eventually
jammed. I unscrewed the end to clean out the dozen or so bits that collected in
The 0.5mm Kuru Toga makes the slightly thinner line than a standard mechanical
pencil, almost the same as a standard 0.3mm.
I don't bother using the eraser as you have to remove (and lose?) the cap. I
guess it's okay for emergencies but I try to keep a standard eraser handy.
Having spare leads included is a real bonus and they are strong and dark.
