The Pentel Sharp P207 is one of the finest mechanical pencils ever made. It’s weight is perfect, the grip is optimal, the clip is removable (which I usually do), and it’s so rugged you can use it to get a rock out of your tire tread and go back to drawing without skipping a beat. With that being said, it has one fatal flaw: The eraser. I’ve been using this pencil for years and would rank it probably my second favorite mechanical pencil of all time, but it has a design flaw that’s never been fixed in its long life time. The metal sheath that holds the eraser in is too thin, causing the eraser to sink back into the pencil every time you use it. Granted: You probably should be using a plastic or gum eraser anyway, but there are always points where you can save time by not switching from the pencil in your hand. As the eraser recesses, the metal sheath is exposed, if you’re not careful, it can actually gouge and tear your paper.
So, it works perfectly until every twentieth line when you have to erase something tiny. I would give Pentel more of a break if they had improved it once in all this time, but, as it stands, I have a new favorite, which I will reveal in a future post. You could do much worse than the P207 (I still keep one with me as a backup), just be careful, and practice safe-erasing.
