Sorry...not used that make. However I did get fed up with using knives that I couldn't get a decent edge on so bought a couple of Wusthof kitchen knives. One of them was a 14cm Santuko knife...works well. Not cheap but have been fine up to now - but that's not what you asked.
But I can recommend this little tool to keep your knives sharp (providing the blade is such that it will take a good edge...I now realise not all do)

This is what you need to (easily and accurately) put a routine sharp edge on the knife but I did also get a decent double sided whetstone to do a more radical re- shaping of the blade angle every now and again.
Sorry not to be more helpful about the Eden knife.
