Uni Shift Pipe Lock Drafting 0.5mm Pencil, Silver Body with Blue Accent (M51010.26)

A couple were purchased for EDC, and they work fine for that. The mechanism for retracting the tip works and is quite novel. It’s a sharp looking unit when deployed and writes fine without breaking much. Some use these automatic type pencils for drafting. What? None of these work well for precision drafting. 2mm lead holders are the standard and have been for decades. Politics aside, if it isn’t lines on tracing paper, these units are pretty good. Some in dismay about this pencil suggest going with something better, at twice the price. I’m not about to carry a pricey Rotring collection around town. Sometimes writing utensils get lost or hammered hard. Carry pencils you won’t cry about if lost/broken/stolen.Addendum: I got to thinking how nice this pencil would be with a few modifications. All metal construction with anodized color where there is now plastic. Reduce width of knurled part to match same diameter of barrel. All metal retraction parts. It would be expensive, but I’d buy it just to look at it now and then, and use it when someone important came in. Titanium for the metal parts would be quite something, though likely out of range....

This is an exceptionally high quality pencil, manufactured in Japan by Mitsubishi, that can be used for either drafting or simply day-to-day writing (which is what I use it for). The body is made of a high quality metal and plastic design, with all gripping surfaces at the bottom made of chiseled metal. The pencil uses a somewhat unique design approach in that you twist the body and push the top into the bottom, which exposes the lead tip. To retract, you push the top down, push the lead in, and the reverse twist. The pencil then expands back to the shape you see in the product image, exposing a very artistic-looking color within the body of the pencil (the color is different based on the lead thickness).Build quality is exceptionally high. It writes beautifully, and when you pair it with the right type of lead, it is a pencil that you can take pleasure in using. It's unique, too, in its style and design, which is a nice touch. And all this for a price that really is not that high, considering what you get for it. I highly recommend it, and rate it is a five star device.

Great pencil that looks cool and writes really well. The design is what sold me on it. A little awkward to figure out how to close and open at first try but it's not complicated once you "get it". It is a little heavier than other Uni pencils I have used and the grip is a little uncomfortable because it is metal and a bit too thick in relation to the rest of the pencil (the upper body of the pencil is plastic). Probably would have been a better design detail to make that top part metal too. Overall a solid choice though that while not as versatile as the other plastic body Uni pencils, it is definitely nice to write with and looks very cool sitting next to your notepad :)

I had been using this pencil for a while. The metal base has a good weight for drafting and keeps the pencil from poking through my bags. The only thing is the top pencil clipper part is so easy to break. I can just break it when trying to clip it to my notebook.

A while ago I got four nice 0.5mm mechanical pencils to compare:- Uni Kuru Toga Roulette : Haven't touched this one in months. It's very interesting mechanically, but the lead wiggles too much and the rotating feature doesn't make enough of a difference for that to be worth is for me. Maybe in a larger lead size this would work better. I have to admit it looks cool though.- Uni Shift Pipe Lock : The retractable lead pipe is nice. I have bent the lead pipe on the staedler and pentel pencils, so keeping it away can help with that. The wiggle isn't too bad but the weight distribution is a bit off for me. This would be a great pencil to throw in the bottom of your bag if you need a draft pencil that can take a bit of a beating. Otherwise see the options below.- Staedler 925 25-05 : My solid #2. Very well made, no lead wiggle as long as the tip is screwed on tight, so writing is smooth. The knurling is a bit sharp but personally I enjoy that grip. I keep one of these at my desk so I don't have to take my other pencil out of my bag. My biggest issue is that the eraser feels a bit loose, but it's not too bad. The price is a bit much for me too.- Pentel Graphgear 500 : Instantly my favorite, and has stayed as such for the couple of years I've used them. The lead pipe is totally fixed to the grip so there is no lead wiggle and I've only had it bend once when it flew spinning down onto tile. The knurling is a bit softer than the staedler, it's a nice middle ground. The eraser feels tight but it does wear a bit fast as someone who makes a lot of mistakes. Just a good pencil, and the cheapest of the lot. That's hard to beat.As someone who does a lot of math and diagrams on paper I pretty much stick to the 0.5mm graphgear now. Alongside it I use the Pentel Hi-Polymer eraser for bigger erasing jobs and a MUJI 0.38mm black pen for dark permanent lines. I highly recommend both of these too, no matter what pencil you use.

Take note, this is a drafting pen - NOT recommended for other purposes - but writing is alright. Take care of the twist mechanism and this will last you long enough. I like the ‘feel’ of the twist lock and especially the retracting lead holder.

Very much pleased with it. The non slippery grip, the retractable tip, and feels comfortable to hold.

Mechanically superior to all my other mechanical pencils. Went ahead and bough the same model for other thickness lead.

Wow, was für ein überengineered, aber gleichzeitig total geiles Teil! Dieser Bleistift von Uni ist wirklich ein Meisterwerk der Stiftentwicklung.Angefangen bei der winzigen 0,4 mm Minen-Stärke, die eine unglaublich präzise Linienführung ermöglicht, bis hin zum ausgeklügelten Mechanismus zum Vor- und Zurückziehen der Mine - hier wurde wirklich jedes Detail durchdacht und perfektioniert.Das Gehäuse aus silbernem Metall strahlt pure Hochwertigkeit aus und liegt fantastisch in der Hand. Und das Beste: Durch einfaches Verschieben des oberen Teils lässt sich die Mine ganz leicht ein- und ausfahren. Das funktioniert so geschmeidig, dass man das Gefühl hat, mit einem High-Tech-Gadget zu hantieren, und nicht mit einem simplen Bleistift.Natürlich ist dieses Übermaß an Perfektion und Präzision für einen normalen Bleistift etwas übertrieben. Aber genau das macht den besonderen Reiz dieses Produkts aus. Es ist quasi der Lamborghini unter den Stiften - unnötig, aber verdammt cool!Wer also Wert auf höchste Qualität, innovative Technik und ein einzigartiges Design legt, der sollte sich diesen Uni Bleistift unbedingt genauer ansehen. Ja, er ist teurer als ein Standard-Stift. Aber dafür bekommt man auch ein kleines technisches Wunderwerk, das einfach Spaß macht, damit zu schreiben.

Very good

Matita funzionale la ricomprerei.

Excelente lapicero, tiene un muy buen agarre debido a que es de metal en esa área y está moleteado, lo de que se retraiga/oculte la punta del lapicero, es muy útil a la hora de alguna caída accidental y no se vea deteriorado su funcionamiento.

Solid pencil... 5/5Writes fluidly and stores conveniently
