rOtring 600 Full-Metal Body 0.7mm Mechanical Pencil, Black, for Precise Ruler-Based Drawing

I’m a mechanical engineer and was going through lots of junk mechanical pencils. They would always wear to the point it wouldn’t hold the led. I then upgraded to a different pencil with a metal tip but ended up dropping it and bending the tip the led comes out.Since then I’ve used this and it’s a great pencil! Very Durable and great design. I love feeling the weight of it when I use it. The tip retracts and prevents your lead or the tip from being broke or damaged. I’ve been using the exact pencil for almost a year now. It’s great to have a pencil that doesn’t wear out. It’s may seam expensive for just one pencil but it’s worth it when it’s something quality enough you make sure you don’t lose and it doesn’t wear out quickly.

I'm not sure why it took me so long to purchase a mechanical pencil. I got this pencil because I had an upcoming standardized exam which required me to use pencils. I must say, this pencil performed flawlessly.The Rotring 600 is all-metal (I believe brass) construction, with a knurled/textured grip made out of metal. This is actually surprisingly comfortable, because intuitively, you would figure that something soft would be more comfortable than textured metal. In actuality, I found the grip very comfortable, but it might not be for everyone -- for example, if like to rub against the grip, it's not very comfortable to rub against (it IS textured metal...). On the other hand, if you want to play with your pencil, the barrel is great for that; it's a hexagonal barrel with a matte finish.The top of the pencil has a knurled knob, for you to turn a little viewfinder-type thing at the top. Printed on the pencil beneath this is 4H, 2H, H, F, HB, B, 2B (I'm going off my memory, but I think this is correct). When you turn the viewfinder/knob, you can set the pencil to display one of these designations, so you know which type of lead your pencil is currently filled with.Above this is the clicky button for you to dispense lead. If you pull off this cap, there is the proprietary eraser unit underneath. If you pull out the eraser unit, you can fill the pencil with quite a number of pencil leads. The one flaw here is the eraser. I didn't use it much, but I imagine it would be difficult to use. To use it, you have to take off the normal clicky button cap, thereby making it prone to be lost. I also think (again, don't have the pencil with me) that it might be prone to click the lead if you use the eraser. Finally, since it's proprietary, you will have some difficulty (and expense) obtaining replacements.The other potential issue I found is that the tip of the pencil is a hollow tube. When you click the top, lead comes out of the thin tube. However, it seems pretty unprotected. For example, I don't know what would happen if you dropped the pencil directly on its front tip. I suppose it could actually be very sturdy, but I was a bit nervous that I might drop it and bend the tip, breaking the pencil. (Rotring also makes the Model 800 which retracts the tip to avoid this situation completely).Overall, I really liked this pencil. It's got a really solid feel to it and seems to have great build quality. If you want a high quality mechanical pencil that will last you for a long time, I recommend this.

Bar none, this is the best mechanical pencil I've ever owned.

A friend referred me to this amazing machine. At first, it was different from my old cheap mechanical pencils, but it was a welcomed change. I got it for my first year at university, and I have only needed this one so far. I have never lost the pencil and I get compliments about it all the time! A good weight, rigid, and accurate. I'm not an artist so this is purely coming from someone who is a Mechanical engineering student, so mostly arithmetic, diagrams, and basic notes.P.S. Definitely gives me comfort on an exam because it makes me feel just a bit smarter lol ;)

Coming from Kuru Togas, Graph Gears and Sumo-grips, I have used a wide range of mechanical pencils and I am grateful to have found this gem. You don't realize how great a simple pencil can be until you are handed to write with this. Exceptional build quality and writing comfort!

The pencil is worth every penny. I’m a math major in college, and I’ve already filled up an entire notebook with this pencil. It feels great to write with due to the weight of the solid metal body, the knurled grip and the hollow cylindrical tip. It feels precise and durable, which is what I had hoped for when buying it.The downside is the eraser setup; buying more is annoying and they only come in packs of 3,4 or 5. Of course, one could easily use one of those large parallelepiped erasers (the pink ones or white polymer ones) and not buy those tiny replaceable ones.If you want a pencil that will last for years, this is an option. If you write a lot, don’t cheap out on your instrumentation like I have for so many years.

The price is a bit steep for a mechanical pencil, but I can't deny the high quality manufacturing of this thing. It feels solid and hefty like it was machined from a single piece of metal (aluminum?), and the knurling feels awesome. The pocket clip feels solid and it seems like it will never come loose. I think my favorite part is the rotating lead hardness indicator. So if you change from HB to 4H lead, or if you have more than one pencil with different leads, you never have to guess which one is which. It spins smoothly but never spins unintentionally so there is no worrying about that.There are really only two things that keep it from being the perfect writing/drafting tool:1. the eraser is ridiculously tiny. So either get some refills or get one of the brick style erasers to keep handy.2. the tip does not retract and I am constantly worried that it will bend or break. Considering the price on this pencil it seems like a huge oversight that the tip is constantly just hanging out there, seemingly just waiting to get wreaked. As much as I was hesitant to pay 25 dollars for this pencil, I would gladly pay an extra five to ten dollars for a version with a retracting tip.While the sanctity of that tip scares the pooh out of me, I can't deny this is, by far, the best pencil I have ever owned and if it does break I think I will shell out the money for a new one.

Love this pencil. Super sturdy and holds just the right weight.Use it for school all the time and the lead holds firm
