Pilot Mechanical Pencil Automac, 0.5mm, Diamond Silver (HAT-3SR-DS)

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. 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.

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 advance automatically, 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."

I bought this mechanical pencil out of obsession, they worth a dozen more ordinary pencils but I am glad to have it after weeks of use. The built quality is comparable to Uni Kuru Gora, and in some extent even Rotring. It has a ball-point-pen like retraction system which works quite well. (although it does pushes the lead at the same time, but not long enough to make the lead go outside the cover) The writing experience is also a very soft one comparing to Rotring and perhaps resembles the most as a Platinum. The tip does move quite a bit, for precision drawing it is probably not a good sign but for me it is just as good as a Rotring.

it does auto advance little but not enough to use without some help, i would give it four stars if it had a twist erase

Awesome mechanical drafting pencils. Pilot used to make a similar black retractable pencil in the 80's and they stopped making it. This one is just as good. Solid, all metal, and you never have to worry about bending your 5 mm. tip--it clicks back up into the pencil like a ball point pen. Appears only one seller has these, and they ship from Japan, but the two pencils I bought (one for me, one for my high school student) arrived in USA 3 days prior to the earliest estimated shipping/arrival date. Love these things, and have been searching the internet for them for years. May even buy a couple more to tuck away in the event me or my son lose ours, and Pilot quits making them. They are that good IMOH.

Quit working properly. When I press down to write, the point collapses back up into the barrel.

I really like the weight and the look, but it doesn't seem to keep the lead loaded in the end of the pencil.

昔ファーバーカステル社から同様のシャープが販売されていてとても気に入っていましたが、長年使っていて流石に芯がスムーズに出なくなり、修理に出したいなと思っていたのですが販売終了から随分経っていて無理そうなので探していました。このシャープ以外にも同じような機能のシャープが販売されていて、５～６種類購入して使ってみましたが、これが最高でした。デザインなどは好みなのでしょうけど、私はこれが気に入っていて予備も持っています。余談ですが、随分昔に販売停止になったPILO Automacで全くノック部分がなくて自動的に芯が出てくるタイプもこれも凄いです。こっちは芯を掴む部分がひっこなまいのが個人的には残念な部分でしたが、メカは本当に素晴らしいと思います。Pilotさんにこれからも頑張って欲しいですが、オートシャープについては完成形と思うのでこれ以上の発展はなさそうだし、なくても良いかなと言うくらいの感覚です。

メタルボディでプラスティックのものと比べ重みがあるため、落ち着いた滑らかな書き心地です。芯先も収納できるタイプなので、万が一落としても芯先を曲げる危険性を回避できます。愛用できそうなシャープペンでした。
