Uni Mechanical Pencil Kurutoga Pipe Slide Model 0.5mm, Black Body (M54521P.24)

This pencil is awesome for its price point.I only have two complaints about this product:1. The rotation mechanism requires a certain amount of vertical pressure to activate. I tend to do a lot of my lettering from a lower angle (pencil at ~ 45º relative to writing surface instead of 90º). This means I'm not activating the rotation mechanism when I hold my pencil like this.2. The pencil would feel nicer with a bit more weight.Despite those two complaints, I'm still giving 5 stars. I understand there are limitations to the rotating mechanism and I'm fine with them, especially for the price. Additionally, I'm aware that there is another model at a (slightly) higher price point that has a metal and heavy plastic body that would satisfy my weight complaint.Another note: the lead retracts ever so slightly into the body as you write in order to activate the rotation mechanism. The slight slack in the pencil took me a while to get used to, but now that I'm used to it, I don't notice it anymore.Otherwise, this pencil rocks. It's a powerhouse for the price and functions exactly as intended. The clear window to see the mechanism is helpful to see if you're writing at the correct angle to engage the mechanism; plus, it looks awesome. The included lead and eraser are smooth and feel high quality. My lead is always sharp and my handwriting looks much more consistent than ever before. I would definitely recommend this pencil or another in the Kuru Toga product line.

Arrived on time. It is a well constructed mechanical pencil that looks good, but alas, it just arrived a couple of days ago and I haven't had time to really use it so on that most important part, I cannot comment.

The Twist-Erase and Pentel Sharp Kerry mechanical pencils owned this heart since 2009. My only complaint: the need to deliberately break the point at times to re-awaken sharpness. The older Kuru Toga models were better on that score, but reliably uniform sharpness throughout a page proved elusive. That scenario ultimately landed me on this page.Arriving a few hours prior to a webinar, this mahhhhvelous instrument proved it's delightful prowess as I wrote pages of notes. This pencil may not be as ultra comfy as the Kuru Toga Alpha Gel models, but the sharpness factor rules supreme. The Alpha Gel's squishy grip spoiled me, so I'm adjusting—with a smile! No hassles, at all, with the rotating mechanism. The sleeve extended as expected throughout. Indeed, after a few minutes of writing, I forgot about it.I'm sticking with 5 stars despite the laughable eraser. No way this munchkin is worthy of the 3 syllables of its name. I cured that problem with a Campus 2B eraser (JetPens), since I use only 2B lead. (Worth the hassle: erasures are super clean, no smudges, no paper trauma, & a minimal debris trail!). My plan now is to grab a few more of these gems, so the pencil will be situated at each of the prime spots in the house, my EDC bag and car. Ditto the Campus erasers. Unbeatable combo, especially since I'm a faithful bullet journaler who prefers pencilled rapid-logging.Special note: The pencil appeared to be stocked with only 2 (HB) leads. After popping off the eraser, I opted to drop in only 2 2B leads. Didn't want to risk jamming it, as I imagine the hallmark mechanism is somewhat sensitive. And, I'm using the Kuru Toga lead. Not sure if that's the reason, but despite being a masher (heavy handed), I experienced no lead breaking.

I've been using this Kuru Toga with Uni's Nano Dia 4B lead. 4B is a very soft lead that lays down dark lines, but wears down quickly. My hope was that the lead-rotating mechanism would be fast enough to keep a sharp point on the paper at all times. My verdict is that it's *not* quite there. If you're printing or writing numbers, I think it works well. But if you are sketching longer lines or writing in cursive, it doesn't seem to rotate quite fast enough. I'm going to test this with 2B and HB leads as well.Ergonomically, the pencil is light (good for handwriting, not great for drafting) and feels comfortable to the grip. I haven't had any noticeable wobble in the sleeve. And the tip retracts, which makes it great for pocket carry.The biggest downside to this (and many) mechanical pencils is the teeny tiny eraser, that is clearly designed for people who don't make mistakes. You should go ahead and buy a pack of Type S Uni eraser refills, because you're going to need them.

This product is a fantastic find! It's reasonably priced, making it accessible for most budgets without compromising on quality. The product is exactly as described, and its usefulness cannot be overstated. I've found it to be incredibly practical and efficient in meeting my needs. The attention to detail is impressive, and the performance is on par with more expensive alternatives. If you're looking for something reliable, well-made, and at a fair price point, this is the perfect choice. Highly recommended!

I hated having to rotate my pencil when writing as staying on one side and the angle in which I write makes the lines thicker. Now I can keep clean and crisp lines through. Really makes my hand writing look neater. Very happy with this crazy technology of rotating led in a pencil. Now I want the more premium ones.
