I have the 1000/4000 grit stone. I bought it a couple of years for my chisels and carving knives.
This stone works excellent on my broadheads. I use it on all my broadheads at the start of hunting season and use this stone to touch them up threw season.
Now I don't use a jig, I have always been able to sharpen stuff. Just all the years of practice I guess(been sharpening my own blades since I was 14, I'm 35 now). But I have been thinking of getting a jig just so I can speed the proccess up.
But I love these stones, easy to take care of and no oily mess.
