Yes I grind out part of the spine a little, I did not reach tang really, I also strighten handle bit more then I did it for spine. And to my taste it looks better then original, also it gives some little bump for thumb to push knife better. And of course there is not gap between blade and handle to catch water, bacterias, dirt etc...
Yes, I love it! It appropriately connect thin handle with thick blade from design point of view. Before it was like to unrelated pieces, but now it play together much better.
Thanks, Vassili.
