A little while back I introduced you to Kreedo Academy. Although I have sharpened my own knives already for many years now, I found new ideas in the comprehensive online course.

So, now I have given my reed knife a new finish. Now it radiates with a new shine and is sharper than it ever was.

Ever since my very first reed I have owned the same reed scraping knife. I have had it since my earliest years of lessons at the music school with my first oboe teacher. It has a very slightly hollow ground shape on both sides and over time has acquired some rust.

The hollow ground shape makes sharpening this knife somewhat demanding since one can’t directly sharpen it. This knife is made by the manufacturer with a curved sharpening stone with a diameter no one at home can reproduce.

My first reed knife: slightly hollow ground, on the sharp edge there is a micro bevel and there is some corrosion.

Mein erstes Schabemesser: leichter Hohlschliff, am Grat ist ein Mikroschliff hinzugefügt und etwas Flugrost

My first reed knife: slightly hollow ground, the edge has a micro bevel and a bit of rust.

Nevertheless, one can of course sharpen one’s own hollow ground knife. This is best done by making a micro bevel. By doing this, the edge is given a slightly steeper angle, and this causes it to be sharp.

With time this [micro bevel] has become quite large on my knife. In addition, the knife has become thinner in the middle compared to the ends at the tip and at the handle.

At Kreedo Academy I learned that this is relatively easy to remedy since one can make a slightly hollow ground knife into a beveled knife.


A diamond plate removes much more material than a sharpening stone.


In order to remove the somewhat large micro bevel, one needs a diamond plate. A sharpening stone will not function for this because it is much too fine. The goal is to remove relatively large amounts of material in order to get an even edge.

By placing the knife flat on the plate, the hollow ground knife gradually changes into a beveled knife. This will make future sharpening much easier. As an added bonus, the rusty spots also disappear slowly. It is possible to help the rust removal a little if necessary, with some sand paper.

The knife clearly show the gradual transformation from double hollow ground to beveled

The micro bevel gradually disappears













Sharpening with a Japanese water stone

Because the sharpening process on the diamond plate is very coarse, it is important to follow up with a much finer sharpening stone. I used a Japanese water stone. Naturally, I started by using the 1000 grit stone and then later the 6000 grit stone.




Slowly the reed knife begins to shine

In the next step I cleaned the edge with a leather strap so that I would achieve an even sharpness. This way I can avoid catches in the reed while scraping. For some quick maintenance during scraping I use the leather. The more often one does this, the longer one can put off needing to return to the sharpening stone.


Compared to before, my reed knife is significantly sharper and looks better maintained. The matte stripe in the center betrays its history as a hollow ground knife. This will gradually disappear more and more with each new sharpening. The advantage of the beveled nature of the knife is simpler sharpening since it no longer has a micro bevel.

You can learn the exact procedure for dealing with the various sharpening tools at Kreedo Academy. In addition, you will be introduced to different types of reed knives and sharpening possibilities. The online course is so comprehensive that in end you know everything about sharpening knives.

To get to know it better, I definitely recommend trying the free tutorial!

And now if you decide to go for the complete access, you can choose between a monthly, yearly or a lifetime subscription. Each of these variants includes a 7-day free trial with access to all content.

The pilot project “The Knife Sharpening Companion” shows not only how to sharpen different types of knives, it also takes on the topics of different kinds of knives and how to work with various kinds of sharpening tools.

Christel and Jürgen Krebs have enlisted the cooperation of the experience oboist, Jeanine Krause for this project. Together they introduce the materials and the types of knives and discuss the advantages and disadvantages on camera. They consciously chose English in order to reach a world-wide audience. The clear vocabulary and video transcripts make it accessible and understandable even to those with more limited fluency in the English language.

Oboe Blogger David Werner puts Kreedo Academy to the Test

Oboe blogger, David Werner has a passion for oboes and reeds and keeps himself and his readers informed of all things pertinent to oboists on his expansive and aesthetically pleasing website, OboeBlog.de.

He made Kreedo Academy and our first large-scale online resource the subject of his blogging. He wrote two articles and in the second he put our Knife Sharpening Companion to the test by diving in and using it to work one of his own knives, detailing his journey in word and image.

Was he successful in sharpening his knife? Find out by visiting his blog. We’ve also included an English translation in the “News” section of our Reed Room here at Kreedo Academy.

COMING SOON! The Knife Sharpening Companion

We are very proud to announce that Kreedo Academy will launch its first comprehensive product in the beginning of 2019. 

We are so excited to share this after a year of building and preparing and testing. The Knife Sharpening Companion is a guide to knives, sharpening tools and their selection and care.

When we founded Kreedo Academy at the beginning of 2018 with our mission to develop a clearinghouse for double reed players worldwide by providing connections, tools, materials, concepts and resources for reed making, we needed to decide where to start. The natural answer became obvious to us very quickly.

Skillful reed making begins with a sharp knife!

Follow this link to watch a short video detailing the Knife Sharpening Companion.

Join us in our first large-scale endeavor!

Granada, Spain: Jeanine meets new IDRS President Eric Stomberg

With a backdrop of breathtaking Andalusian flair, complete with Flamenco, Spanish hospitality and warm summer nights, the 2018 IDRS Convention took place in the shadow of the dramatic Alhambra palace in Granada Spain.

While in Granada, I had the great pleasure to meet the new president of IDRS, Eric Stomberg after our Spanish hosts led us in a successful bid for a Guinness Book World Record.* The oboe band open air extravaganza commenced mercifully at 11 at night, meaning temperatures were still warm but not debilitating. The hour had the distinct disadvantage that the tapas bars were closed by the time we had packed away our reeds and instruments, ready to celebrate our victory. The Orquesta Ciudad de Granada (Granada City Orchestra) Cellist, American, Kathleen Balfe graciously invited me and Eric to the rooftop terrace of her home. In addition to Granada’s splendor and a full moon, we enjoyed excellent food, drink and lively conversation.

IDRS Granada 2018

Eric has long been actively involved in IDRS and has stepped up to the post of president in January 2018. He’s witty and intelligent and seems to have a sharp sense of business combined with that invaluable skill, empathy. He would probably be a great success in the world of the free market except that it is so clear that at heart he is a musician, a teacher and a passionate administrator through and through.

IDRS is in good hands with Eric Stomberg!

Be sure to visit the new and vastly improved IDRS website!
