My name is Karstein Grønnesby – blåsemakerA maker of wind instruments. The word is composed of «blåse(instrument)» (wind instrument) and «-makar» (maker). from Steinkjer, now living in Oslo.

The instruments are rooted in tradition and craftsmanship passed down through generations – learned from some of Norway's foremost tradition bearers.

Bought a Meråkerklarinett from Blåsemaker Grønnesby earlier this year. The clarinet arrived well packaged, with two custom-fitted reeds, and has a good sound. I get quick replies to all my questions. I forgot to order a bag for my clarinet, but that gave us an excuse to meet and have a chat when he brought a bag for me while he was travelling.
Pleasant man with a lot of knowledge who does good work.
Thank you for creating this instrument :) It's a lovely instrument with a beautiful sound!!! Well done on this creation!!!
I live in Turkey, and my friend was travelling to Norway for a vacation. After doing some research, I found this website and reached out. The seller answered all my questions sincerely and delivered my order to my friend without any issues. It made me very happy to come across such a kind and trustworthy seller from another part of the world. I want to thank him once again for his great work. Additionally, the instrument he crafted is truly priceless.
“We wanted a horn with real history behind it, not a souvenir. Karstein is one of very few people in Norway who can make instruments like this, and the result was exactly what we had hoped for. When the horn sounded in the stands at the World Cup, it set off the rowing for thousands of Norwegian supporters.”
