Review – Kokuyo PS-FP102 Mechanical Pencil (.7mm) (DM)

In a time where a lot of companies are trying to re-invent the wheel with their pencils, Kokuyo from Japan has made a relatively inexpensive, minimalistic, and comfortable mechanical pencil. The PS-FP102 (Pencil Sharp {my guess from the website}) omits several things that could be thought of as standard, and uses that effort on a sturdy and comfortable design (that is, from what I understand, ostensibly for children in school). Is the trade-off worth it?

The body is one of the simplest to be found on a mechanical pencil, being mainly a vaguely triangular-ized (at least the “frosted” versions are triangular) cylinder with a rubbery coating for the 4 ½” body. Sticking out a quarter of an inch on the back is the click-advance button, and five eighths on the front is a plastic cone, from which a smaller metal “lead-pipe” can emerge bringing the total length of the cone to three quarter inches. Printed (maybe stamped or adhered) on one of the facets is all of the information about the pencil (which seems like it will rub off in the future but has withstood use so far).

The body can be unscrewed at the cone, revealing that the rubberized triangular barrel is just a sheath, and the cone mechanism can be pulled from the front. As far as I can tell no further takedown can be done and neither of these operation provide any real benefit that I can see beyond checking how much lead is in the pencil (through a convenient window {the view on my frosted black version from the outside is blocked}) and perhaps clearing out the front mechanism.

Writing performance is good; the lead is a .7mm and presumably HB (there are also .9 and 1.2mm versions). It’s a bit too thick for what I usually like to write with (.5mm) but it is fairly break-resistant and smooth, which would be good qualities for a school pencil, and from what I understand that is what it was originally designed for. There is no eraser or clip (though there is a version of the pencil that comes with a stand-alone eraser and friction-fit clip) and instead of having to remove a back piece to insert lead there is simply a hole just big enough to fit the lead through that lead can be fed into. Once it has been pushed all the way in, it enters into a larger reservoir and will not likely find the correct angle with sufficient force to come back out of the hole. It’s honestly a pretty elegant lead-feeding system if one doesn’t care about having an eraser.

The click-advance mechanism is very smooth and workable, but unsatisfying. The metal “nib”/lead-pipe at the front does retract and advance with the lead, neatly preventing any damage that it would cause but being a bit fiddly (it’s easily possible to retract the lead and not the metal piece, which is a bit of a strange situation). And the rubberized, triangularized grip is very easy to hold, not slippery at all, and quite comfortable (though not my preference), especially for hands just learning to write (it keeps fingers in the proper orientation). I must say, though, that it only barely resists rolling off the table more than its round counterparts.

So instead of an eraser or clip, this pencil provides an elegant lead-feeding system, comfortable and chucky triangular grip, and a stow-away point. All of which make it a good fiddly-bit-free pencil for students, and with a slide-over clip and external eraser (the integrated ones are never enough) it might also be a preferable one for artists or in the office. For the mostly reasonable price of ¥180 (≈$1.55) it’s a solidly designed, well built little pencil that seems like it would last under a bit of stress and is certainly worth checking out if you want a triangular grip or to forgo the standard integrated eraser for greater lead convenience.
