  Years ago Mitsubishi..., October 25, 2008
By hartzog2000 - See all my reviews
Years ago Mitsubishi made these for Faber Castell under the name TouchMatic. They only came in black. The eraser was so small that I could get into tight spaces with it to erase fine detail. I liked the TouchMatic so much that I bought a box of a dozen just to get the refills. When I ran out of refills I was dismayed to find that they were no longer available. I looked on line time and time again for them to no avail. Then I came across the E-Knock. I discovered, to my delight, that it was the old TouchMatic reincarnated! I was elated! Now I not only have a new source for the refills I have a choice of a few delightful colors for the bodies as well. Kudos, JetPens, for bringing delight to this old heart.

  Slightly misleading,..., April 10, 2009
By todavecave - See all my reviews
Slightly misleading, the eraser is actually only 5mm wide, not 10mm. Unless they were talking about the tube itself which just seems odd. If you notice the print at the top of the tube says medium which means there probably is a large version that has a standard 10mm eraser in it. Would be fantastic if Jet Pens carried it!

Soft eraser, easy to erase slim lines, dark lead tends to build up fast on the eraser and smudge so I recommend using a harder=lighter pencil lead 2H-4H if you want to use this eraser regularly. Solid construction, simple mechanism, I like the fact it is see through and that you get a good amount of refills for a fair price...

By backgammoner - See all my reviews
I have been using this eraser for about 2 weeks now and I am really pleased with it. It is comfortable to hold and use, the clip makes it easy to attach to places, it is pleasurable to look at, and erases very well.

My only complaint is that the very top of the barrel has cracked (I am not sure how it happened), it is not affecting the performance at all but I hope it doesn't get worse.

As an engineering student, you go through a lot of lead and erasers. I bought this on a whim and it works wonderfully! Too much pressure on it can make the eraser slip back into the body. Overall, great quality. You may want to buy the refills. The one provided lasted me about a month a half / two months. My go to eraser next to my Tombow Mono block eraser!
