KUM Correc-Combi 10

Today I want to show you KUM’s Correc-Combi, a sharpener in an eraser case, which I bought this April for €2.79 (~$3.65; £2.25) in Müller in Volkach, Germany.

The eraser

The blade of the sharpener is fixed to a plastic body which in turn is encase by (quite a large) eraser. I am sure it will take quite a long time to use this eraser up.

The sharpener

The performance of the sharpener is quite good, certainly much better than the performance of KUM’s 400-1K. The sharpener produces thin shavings with an average thickness of 0.2 mm1.

I also saw a set square from Globus by KUM for 49c (~ 65¢; 40p) in the same shop and couldn’t resist buying it. You might remember the list of sharpening angles of the different sharpeners in the KUM 400-1K blog post. When I figured these angles out, two years ago, I didn’t have a set square – so this time figuring the angle out was much easier. With about 22° the sharpening angle of the KUM Correc-Combi is very similar to the sharpening angle of Möbius+Ruppert’s grenade.

Conclusion

A very good sharpener/eraser combination. The lid fits well, despite being a ‘click in’ lid (no screw thread) . The performance of the eraser is similar to that of KUM’s Correc Stick. It could be better, but is by no means bad. The performance of the sharpener is quite good and overall this eraser/sharpener combo offers very good value for money.

I would like to thank Hen Chung from RAH for the Staedtler norica 132 46 HB you can see on the photos. It’s the less purple version with blind stamped “SRP”2.

The Correc-Combi is part of KUM’s Blue Ocean series. You can read a review of KUM’s Blue Ocean pencil set at pencil talk. You can also read a review of Staedtler’s norica at pencil talk.

In a previous blog post I wrote about Faber-Castell’s sharpener-eraser pen.

  1. I recently bought a calliper in Lidl, so I thought the thickness of the shavings would be a good thing to measure, especially since Lexikaliker mentions the thickness of shavings in his blog. []
