Lofting from rectangle to cylinder face creates a spiral. Trying to create a screwdriver tip.

Hi there. 
I'm making a purpose-built screwdriver but the tip is coming out funky. 
Lofting from Plane 1 to the face of the extrude creates a spiral sort of twist. 

Any way to correct for this to make it look more like a real screwdriver? 

It works, and prints fine, just a little detail I'd like to learn from is all. 

Thanks.

The easiest thing to do is split the circle in 4 places and have symmetric relations. This gives the loft command a clear place to connect the sharp corners of the rectangles. You can then tweak the exact dimensions/proportions of the splits to get the shape you want.

 S1mon is correct although I would question if loft is the right tool to use for a screwdriver head.

Aahhh this is amazing. I love the two approaches! Both are great and encourage me to think outside the box.

The loft idea was based on a video tutorial so I followed it. 
But I like the idea of sketching the tip profile and remove-extruding that.
