Hi! New here. 
I started using axes this fall so I barely have any experience. I bought a big splitting maul which works fine. But I wanted something a bit smaller for kindling etc. and just because.
I've had two heads laying around the house so I restored them and made handles for them.
The heads weigh around 1.3 and 1.5 pounds, and the handles are around 13 and 15 inches long.
My problem is that the handles just don't feel right in my hand. When i'm holding the axe with one hand, after a bunch of small swings it feels like the handle is digging into my hand. The two handles are very similarly shaped, but I barely notice this digging in on the lighter axe. When I have both hands on the handles they feel great.
For the shaping of the edges I did most of the work just by hand with a piece of sandpaper. I tried to make the handle a nice oval shape with smooth transitions.
On the bigger axe the handle is about 0.9" wide and 1.5" high.
Since my only experience is with my splitting which has a fat round handle i'm just not sure what's going on. Is this normal and I just need to toughen up a bit or did I screw something up with the handle? Could you guys share a few handle width and height measurements on similar sized axes so I can get a ballpark idea? I know the shape of the edge is probably super important, I just want a rough idea.
