Uni Kuru Toga 0.5 mm High Grade Auto Lead Rotation Mechanical Pencil, Black (M510121P.24)

I like fine writing instruments. For the longest time during my entire university and grad schooling I used a Pentel Graph Gear 0.5 mm because its heavy and feels awesome when you write. But the lead was always inconsistent, I always had to rotate the pencil because it would get super sharp one side, and if you don't the lead will usually break or give inconsistent widths. This is the problem with virtually all mechanical pencils.Here comes the Uniball KuruToga, which remedies the sharp point problem and constant need to rotate the pencil with its internal rotating mechanism. Not only does the pencil scream Quality, it feels wonderful when you write, especially when paired with Uni Diamond infused lead. The Pencil is made to balance weight and comfort. Bottom half is all metal, while upper half is plastic. This creates a significantly lighter pencil then all metal Pental Drafting Pencil, and yet some heft to add some weight to your writing so you dont need to put as much pressure downwards.It doesn't have the retractable mechanism of the Pentel, but if it did it would be perfect.Complaints about erasers are non issues, just go get replacement eraser, or a standard separate eraser like Tombow.Also BLUE is quite pretty ;D.

In my eyes this thing is engineering marvel. It never crossed my mind the idea that something like a mechanical pen that rotates the lead automatically could exists and much less I could imagine how much this improves my writing experience.I never really liked mechanical pens that much, they always felt like a hassle, having to deal with easily breaking leads and having to constantly adjust the pen in my had to get a fine line was an annoyance, so I always preferred normal pens. Now that I'm studying Japanese again, I decided to try again a mechanical pen, someone recommended this and oh boy I could not be happier with it, practicing my kanjis with this feels like a god sent. Whoever came up with the idea of building pen, I salute you.

Despite being a huge technophile, I still have some habits that would be considered by many as idiosyncratic anachronisms. Perhaps most prominent of these is the way I still take notes and explore ideas: using fountain pen, paper and pencil... and borderline obsessive about the quality of the "old school" tools I use. The tactile nature of these tools usually compel me to test them prior to purchase... and I admit I was a little hesitant (no local distributors around Seattle), but this is a bet I won.The K.T. replaces a fifteen year old Staedtler 0.5mm all-metal favourite that finally broke. Most pencils I've found to be too light or too "fat" or unbalanced... this one is somewhat on the lighter side, but has enough of a decent heft and handles very nicely even for long computation or (technical) sketching. The thickness of the barrel is on the average side for what I prefer/use, but feels right and has yet to make my fingers feel fatigued.I was skeptical about the "auto rotation" mechanism --- wether it makes any difference or even works --- it seems to work really well, maintaining a nearly constant width point. The only gotcha is I have to 'unlearn' the reflex which I've developed of rotating the barrel with my thumb every time I lift the instrument off the page. I don't have to.Minor wish: it's a hybrid, metal with few plastic parts. An all-metal option would be great; just a bit more weight. This almost docked a 1/2 star from it, though its good enough overall to be pushed up to five for the autorotate.Since it's new, durability of both the mechanism and the finish is TBD, after some weeks in the field.

Very good pencil

Pencil feels great on hand-- super sturdy ,& steady. Eraser is super- tiny, though

I used to think mechanical pencils were fussy. This one has converted me.

Pricey for everyday use, but worthwhile for technical or precision script or sketch.

Bought this because i'm tired of having to resharpen my standard pencils. Whereas most mechanical pencils break under my pressure and feel cheap.-This pencil uses some sort of pressure dispenser allowing the pencil lead tip to take a lot more pressure than other mechanical pencils. I think i've broken the lead tip once - when i dropped it out of my mouth from a high height.-The eraser is a nice design, because it is under a cap, if you lose the eraser you can still use the pencil, without losing all of your led, and the eraser is small allowing for precise erasing. I'm not sure if there are replacements that you can get, but they could have included an extra eraser. Not that i'd be able to keep track of it anyway.-Feels really solid and nice touch. Everyone who uses it comments on how nice it is. Spending ~$14 on a pencil might seem a little steep but this is certainly worth it, and you'll love it enough to make sure not to lose it. Others stealing it could be a more likely cause of loss.-The auto rotation is NOT a gimmick. My hand has been used to rotating the pencil manually for the sharp side, but after awhile you adjust. Then when you use someone else's pencils or leave this one somewhere, its disturbing how their lead goes from sharp to thick and you have an inconsistent thickness line/text.
