Mobius+Ruppert Sharpener Blade M+R Refill 10 Units, 1000050, No Color

I have a half-dozen hand-sharpeners from many brands... Alvin, Koh-i-Noor, Staedtler. So far, no problems and all seem to perform better than ever. I don't really understand the plastic case: it's not like I'm going to sit at my desk on Monday morning and say "hmmm, which pencil sharpening blade shall I choose today?" and then laugh manically, knowing the future of my pencils lie at stake. Some kind of cardboard sleeve thing would be better and more enviro. But these seem to be excellent blades. They do make a noticeable difference. If you're looking at an item like this then you know how maddening it is to try to sharpen something like a color pencil and then have the tip break off just when you're about to stop. It doesn't seem to happen with these blades. Or maybe I shouldn't be using blades from the 1980s?

The pack of 10 offers great value, and the blades are incredibly sharp, making sharpening pencils a breeze. This review represents my personal opinion and experience with this product.

Very sharp looks good

Excellent replacement blades for the M&R brass sharpener always at the ready… I will definitely be buying more when needed (have only changed one blade in 6 months of sharpening use.)

$6 for 10 blades seems high but they are great quality and fit most pencils sharpeners. I would suggest getting Alvin blades for the Alvins sharpeners, such as the conte sharpener and bullit. Throwing out all of the ones made in China, they are so cheaply made, you need the ones that are made in Germany only otherwise a waste of money. Will use all my other hand held sharpeners until they start chewing up my pencils and just throw them again and will stick with my Alvin sharpeners. They are the best. If these fit my Alvins, when I try to change then out, I will update this review.

I have not started to use yet but I am ready when the blade I'm using gets dull.

I have both round 2 hole and rectangular two hole. Worked great out of box but when I put M &R replacement blades on they did not work most of the time. They fit the sharpener but don’t make contact with pencil. I’m using sharpener for Fabre castle Pitt pastel pencils. Same size as standard #2 pencil. I will try again in case I got a bad batch (used returned item) as these were recommended for my pencils. Also case is very hard to open.

I am very particular about my pencil sharpeners. I am an artist and love a really sharp pencil. I love the brass M & R brass sharpeners and I have always bought blade refills. BUT...There is a massive discrepancy in the blade sizes that makes these blue packs of ten too big to fit into my M&R bullet shaped sharpener which is my primary one I use. I was very disappointed, so I went back and spent a lot more money on the M&R 3 pack, thinking that maybe the ten pack was some kind of knock off. Today I tried out all the blades and found out that the pack of ten fit the round and two blade pencil sharpener and work well, and the 3 pack is smaller and fits the bullet shaped one. It is ridiculous for there to be a slightly different size blade for the smaller one, and certainly no information online that I found to make it clear which M & R blades fit which one! It is only because I love the feel of these sharpeners that I persevered to find out and solve the mystery. Please, M&R be clear with the description of the blade refill packs.. they are different. This information is essential and should be posted in the description to help those of us continue using and appreciating this well made staple of the studio. Now I have solved the problem, I will continue using them as the blades are great and the sharpeners are so satisfying to use.
