Hey nice looking mallets. I've never really got on using mallets in my day job, but hobby wise having a mallet might be a good thing. I like the idea of making it out of one solid chunk rather that forming a head with an handle inserted into it. Clever thinking that.
As for the generous praise that you're finding here. That's one of the things I like about being here on this forum too. People don't sneer or dimiss any decent peice of work that someone has sweated over. and good feedback motivates anyone to keep up that standard or even try harder. Plus the moderators are really on the ball and wouldn't allow someone to flame another.
Credit where it's due mate that's one lovely looking kuska, can't wait to see what it looks like all polished up. Oh and before you get to that stage of the finish have a gander at Wayland's work here at BCUK for a traditional Swedish finish. Here:

About using a stone with glass paper around it. I seem to recall Ayla used sand and stones to smooth her bowl out in Valley of the horses book. nice that you took it to the next logical level. Wouldn't have occured to me to try that techinique had I not been told.
Ok I've blathered on long enough, goona look at the lovely Kuska some more.
