## Questions & Answers

**Q: What is the hardness of the lead that ships with the .5mm pencil?  I like it and would like to match it.**
A: Most mechanical pencils ship with HB loaded in the reservoir. 

I also prefer softer leads, so I have come to prefer Pentel Ain Stein Mechanical Pencil Lead, 0.5mm, 2B hardness leads. I find them smoother that the Pilot premium grade leads of the same hardness, which make marketing claims of diamond dust in the polymer coating.

**Q: Does the built in eraser come with a lead jam clearer pin?**
A: No, but buy a pack/ box of Pilot erasers, jam pins are included. Or just new shirt pins will do the same job.

**Q: Does the point fully retract by clicking the top of the pencil?**
A: Yes it does. The point fully retracts with a full press. With a half press you can advance the lead. Once you get the lead out all you need to do is write with the pencil. The lead will automatically advance as you write. It is a fantastic pencil.

**Q: Seems nicely built, compared to plastic ones but is it comfortable to write with for long periods of time? Thanks**
A: Hello. My pen is in my pocket and I'm using the Pilot Mechanical Pencil Automac all the time/ all around. Yes, i use it for writing too and even for sketching... Try it and you'll never leave it again

## Customer Reviews

### ⭐⭐⭐⭐⭐ Great pencil. Fully retractable sleeve makes it easy to ...
*by T***N on March 16, 2017*

Great pencil. Fully retractable sleeve makes it easy to pocket and safe to carry. Weight and balance is perfect in my opinion. Well constructed. Great looking, again in my opinion. And automatic lead feed works as expected. I loaded up some Pilot 4B Neox lead and it writes buttery smooth. It is hard to describe. Maybe 'greasy' is a better word. However, you really have to try it to realize the difference from the normal HB generic pencil. And finally, it just feels good in my hand. (Not 'the hand,' but my hand. I have no idea what 'the hand' is. People keep referring to how something feels in 'the hand' when reviewing products these days. When they do, I immediately see a mental picture of 'Thing' of the Adams Family. But I do digress.) The metal is smooth but not slippery and the knurling is just right (again in my opinion). And finally, the lead has no play at the tip and I have had no lead breakage problems so far. Overall, I think the pen is great. Great price when ordering it from Japan. Takes a few weeks to ship, but it was well worth the wait.

### ⭐⭐⭐⭐⭐ This is my new favorite mechanical pencil
*by B***L on April 17, 2015*

This is my new favorite mechanical pencil. It is heavy, solid, comfortable to write with, and works well. I consider it to be a very nice "conventional" 0.5mm mechanical pencil. The automatic lead advance will advance the lead for me if I am writing a long note in a hurry or I just forget to press the lead advance, but that's just an extra. One doesn't have to use the automatic lead advance, and this is still a fine pencil even without that.Pros: Solid weight, good construction, and a comfortable grip. You can't see it in the pictures but rather than being sharp-pointed checkering, the texture on the grip is flat-topped grooves and rectangles. That gives a good grip without being sharp enough to feel rough. Also, the point retracts completely for safe and comfortable pocket carry.Cons: Expensive. Has the tiny eraser which is too typical of mechanical pencils; OK for emergency use and it makes a decent stopper for the lead storage chamber, but if you want to do any serious amount of erasing you'll want a separate eraser. I recommend the Pentel Clic Eraser or similar, a stick type vinyl eraser in a plastic tube holder/shell.

### ⭐⭐⭐⭐ A Great Pencil Overall, but not really "Automatic."
*by A***5 on May 22, 2015*

Very nice all-metal pencil. I would give it 5 stars except I find the "automatic" mechanism is not very good--it does appear to advanceautomatically, but only sticks out a sliver. If you want more than a tiny tip, you still have to keep pressing the button.However, the overall build quality is excellent, and I very much like the way the point retracts to save your pocket. It's a great pencil--just forget about it being "automatic."
