1. As you start to write you might have a sharp point, but as you continue to write the point is worn down and thus your line widths are not uniform. This can also lead to smudgy and thick lines.
2. If you pick the pencil up and happen to start writing with the tip of the angled point, it is likely to scratch or catch on the paper.
3. The different angles at which the pencil lead comes in to contact with the paper is a common cause of lead breakage.
The Kuru Toga, on the other hand, has a core rotation mechanism that continually rotates the pencil lead as you write. The lead is twisted through a spring-loaded clutch, it works by twisting incrementally every time you lift the pencil up (i.e. during printing words, etc). This allows a uniform wearing of the pencil lead so that it always remains as a pointed tip. Not only does it solve the above problems, but it also gives you an amazingly thin line. You are effectively using only 50% of the lead area that you were previously using with your old mechanical pencil. Thus, a 0.3 mm Kuru Toga will write incredibly thin lines and have less breakage than a standard 0.3 mm mechanical pencil.

This pencil is awesome....
This pencil is awesome. I would recommend it. You can see your lines perfectly, there's no smudging. the only thing though is that I had to buy an eraser, cause the one on the pencil was too tiny for my tastes. other than that I say go for it! It you like to write alot this pencil is for you!

I like this pencil a lot. The mechanism works well. Usually I give 4's to utencils if there are small defects in them, but I am pleased to say that there are none in this. I would encourage people to purchase the Kuru Toga.
By the way, it writes smooth!

I work as a night auditor...
I work as a night auditor in a hotel and have to fill two spreadsheets in pencil (we're stuck in the 20th century apparently!) In the past I used a Papermate X-Tend Multi and later their PhD Multi, both of which I had to buy again after they break down on me. For the pencil in it (a .5mm) I was constantly rotating the body by thirds as I wrote to keep the lines thin. I discovered the Kuru Toga Engine on Wikipedia and landed on this store's site after a little searching.
This pencil works like a charm for me. The .3mm size is fine to begin with, but the automatic rotating action keeps it very sharp. I've tried the Ain leads in three hardnesses, and here's what I found for writing lots of numbers: The B leads are nice and dark, but they seem to wear a little too fast for the rotation to keep up and look almost like the lines from my .5mm without turning. The HB ones come out very fine but not quite as sharp as the H leads. The HBs are my favorites and work the best for me. The H leads are sharpest and seem to be what the Kuru is tuned for, although I suspect HBs work the best for the shorter strokes of Kanji. I don't like the H leads as much because of their lightness and I have to boost the darkness on the HP All-in-One at work a notch, otherwise the copies I make for management are too faint. I'm going through those leads first, and they do last a long time.
The grip on this pencil isn't as comfortable as it could be—makes the side of my middle finger ache a little. The rubber ring is a nice touch though. The black paint on the side has worn away where the barrel meets the side of my hand where the index finger begins.
The sponginess someone else mentioned isn't bad—I adapted easily, possibly after years of dealing with the Papermate multi-pens which have much more give because of the angle the pencil bit emerges from the body and the manual rotating I did with it.
Coincidentally, the eraser for this is the same size as the one used in the Uni Style Fit Meister 5 pen I bought here. It's a bit small but I normally use a black pearl anyway. I avoided the nicer aluminum pencil because of its blue body, but I am tempted to buy one in the future. All in all, I'm happy with this pencil.

This is an amazing pencil...
This is an amazing pencil if you're into gadgets and technology, because the rotating clutch mechanism is exposed through the clear plastic of the grib and you can see it working with each contact the lead makes with the paper.
The slight edge near the bottom of the grip and the rubber o-ring there make holding it fairly comfortable, but there are also a few issues.
First, the lead breaks fairly easily. I don't know if that's generally an issue with 0.3mm lead, but it seems to require a very light touch. I also find that you can't get through very much text or drawing before having to reach for the pushbotton to advance the lead - again, maybe something that all 0.3mm pencils have in common. I don't have another one to compare it to.
Overall, a fun conversation starter of a writing instrument with a fascinating mechanical feature you won't find anywhere else.

I love the concept of this pencil, and the mechanism is pretty nifty. It does seem like you'd benefit more if you were using a larger lead size though. Maybe the rotation speed should be tweaked a bit so that it turns a bit faster, or maybe it's just due to my style of writing.
The Pencil has a good weight to it, and the little rubber pad is in the perfect place for the way I write. It's good enough that I'd buy it even without the rotation mechanism.
