These pictures are the progressions of the drill icon. Every time I made a change, I printed it out and stood from various distances to see what needed to be changed or tweaked until I got a final icon.
This is the icon has no center white space in the handle. I made these changes to see how it would look without the center. After making the changes I still liked the icon before it because it made it look really bulky. I still need to make some minor changes until it is ready.
I sketched out the trigger again because I was not satisfied with the 1st icon. I made some other changes as well after printing the 1st icon out. I worked in Adobe Illustrator this time to make the second icon.
