Years ago Mitsubishi...
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.

I attend school daily and I can always depend on this eraser to do a well and thorough erasing of my mistakes. At first the eraser can seem rather still, however once you get use to the feel of it, it works rather quite well and works far better than the average Joe eraser.

Works Rather Well

Verified Purchase
Good eraser for those little mistakes. The eraser can get pushed back into the barrel if too much pressure is put on it though.

I purchased two erasers...
Verified Purchase
I purchased two erasers at the same time, for comparison: (1) the Tombow Mono Zero Eraser - 2.5 mm x 5 mm - Rectangle - Black Body, and (2) the Uni E-Knock Eraser - Black Body. Both are very high quality and well made -- far better than other knock-erasers I have owned. I would say that for corrections to handwriting, the Uni E-Knock is a much better size. The Tombow 2.5 mm x 5 mm would be best for very finely controlled erasing such as in artwork, or if your handwriting is very tiny.

Great precise erasing. Works as intended. Can run out pretty quickly if this is your main erasing tool.

Verified Purchase
For erasing small items, I used a Tuff Stuff for years until they were discontinued. This is the best replacement I've found and actually outperforms any other stick eraser by a long shot. Very smooth and erases marks completely. You won't regret buying this--make sure to get some refills.

Eraser is ok but not great. The plastic body cracked where it has a screw-in tip, got to reorder until better one is produced.

Verified Purchase
I love this little handy thing, but i was surprised at how slim the eraser was. I don't mind the thin eraser, it erases perfectly in between the lines. I bought 2 just in case 1 broke, and a pack of the dust-gathering eraser refills (they fit in this model perfectly). I highly recommend this, but be sure you know if a 5mm diameter eraser is either a pro or con for you.

I really liked the eraser...
Verified Purchase
I really liked the eraser at first, but after just a couple of exams the clear plastic, near the tip where the black piece screws in, cracked in 2 places. It is now very difficult to erase. I'm very disappointed to write this review, but I hope other people take caution before purchasing this product.

Verified Purchase
the Uni E-Knock removes .5mm 3B lines well. I am pleasantly surprised at how precisely I am able to erase around my small writing.
Though I enjoy using this eraser very much, I have had the same issue as another owner with the barrel cracking at the threads where the black tip screws on. When the tip comes loose the eraser wiggles around in the barrel and becomes difficult to use. The clip also broke on mine, but that did not affect the function in my case.
As a hack fix, I wrapped several turns of a thin wire around the outside of the threads and taped the wire in place so the cracks cannot expand and allow the tip to come loose. This has been working well for a few months, but I am disappointed that the plastic fractures so easily.
