Hello Emily! Thanks for such a quick reply. Nice job on this site - I've just started on vavraharp.com and will turn it over to you for overhaul soon :)
Now, about the dual action sharping levers. They're for real. I'm a mechanical/electrical engineer gone into software engineering... A passion is building harps and I couldn't find a sourc for conventional pedal actions so had to come up with something. I planned, experimented, drew plans and wrote specifications then hired patent attorneys. It all went down hill from there. The patent app is ready for submittal as a 20 year utility patent and they're sure it will go through. However,, I'm nearly 70 and just want to build harps, not mess with making levers.
So my goal is simply find someone who wants to take it from here so I can build harps and THEY can make levers. Seems straightforward enough to me.
Let me know if you can think of a way to get the 'biggie' lever manufacturers interested.
