tried to fix handle
Okay okay-
1. Make a rectangular prism.
2. Extrude long, thinner sides.
3. Then size them down, so when you view the grip from the bottom, it's like a strectched octagon.
4. Select the 4 back edges of the grip, while it's standing up vertically.
5. Then subdivide.
6. Move the top part a little to give it a curve.
7. Rotate, and now you have a grip.
