A 1000 grit stone is pretty fine so you might want to start with a more coarse stone to get the geometry you seek.
Starting with inexpensive knives to hone (pun intended) your skills is a great idea. When I got my 1x42 grinder I didn't start off with my finest blades. I rooted around for those cheapo knife sets everyone seems to have hanging around (and sometimes still using) to gain some muscle memory. Keep at it!
