An alternative approach to modeling this handle similar to how it was probably manufactured "Stamped":
Start with a flat version spine the two prongs in the front. Add three Loop Cuts where the edges of the side pieces are. CTRL + R
In the tail end of the mesh add a bunch of Loop Cuts. I used 30. CTRL + R Mouse wheel to 30.
Select the following Edges and place the Cursor approximately here and use the Spin Tool ALT + R You can adjust the angle and increments in the Tool Panel (Pressing T toggles the panel on/off).
Extrude those same edges down a bit E + Z
Select the following Edge and Extrude down some more E + Z
Select the following Edges and Extrude theem down E + Z
Hide everything but the following.
Enable Proportional Editing with a Linear Falloff and scale the bottom Edge inward S + X
Select the bottom middle Vertex and change the Falloff to Sphere to create the following shape.
Select the back edge and change the Falloff to Sharp and drag down to create this shape G SHFT Y To constrain the movement to the x and z axis.
Disable Proportional Editing. Change the Pivot Center to the 3D Cursor. Select all of the following and Rotate on the Y axis R Y
