Nearly useless. Not only...
September 23, 2014
Nearly useless. Not only is it subject to the same skin oil incompatibility
problem as most Pentel erasers, where if you use an eraser shield or brush off
the eraser with your fingers it will DRASTICALLY reduce erasing power and
produce uneraseable black smudges on the paper, but it also fails in areas where
it's supposed to be uniquely suited for.
Its form factor, which is supposed to be its selling point, makes it hard to
reach sufficient pressure to erase. When used on the broad side, the eraser
folds and the erasing area increases, dissipating and spreading applied force.
When used on the thin side or on a corner, you do get better pressure, but the
thin side is not very different from using a block eraser's edge, and corners
can easily break off. Produces a lot of small, fairly messy clumps. Difficult to
handle for big hands like mine. Sleeve slides around very easily, too much so
At least Pentel's Light Erase and Dust Gathering, which have the same issues
with skin oil, have the redeeming qualities of their unique mechanical
properties. My advice is to look at the Kokuyo Campus erasers for your lead
grade (B/HB or 2B, I use the B/HB variety with 0.3mm B lead). If you insist on
wanting to try using this eraser, here are my tips for best results: place the
sleeve VERY close to the erasing end (a couple millimeters), erase with the thin
side or a corner by being careful, avoid touching the tip of the eraser (if you
do just wipe it off on a piece of scrap paper). If you do that then this becomes
a somewhat more precise than average eraser with fairly unremarkable erasing
In conclusion I'd say that small form factor erasers are a gimmick. If you are
familiar with your block eraser's softness and required pressure to erase, you
can erase very precisely. Even better if you have an eraser that starts erasing
quickly at a lighter pressure, such as my Kokuyo or Pentel's Light Erase. If you
have an exceptional need for the utmost precision, you would be better off
looking at electric erasers. I haven't had the chance to try any, but their
rotating action completely eliminates travel and I think that's the way to
achieve ultimate precision, if that's what you need.
