Day 9 - Screwdriver

It's a Phillips screwdriver (no it's not, it's mine)

Created by Henry F. Phillips, the Phillips screw drive was purposely designed to cam out when the screw stalled, to prevent the fastener damaging the work or the head, instead damaging the driver. This was caused by the relative difficulty in building torque limiting into the early drivers.

See, this challenge is educational too

  1. Oooh, I love the shallow DoF in this one and the composition is lovely. Immediately recognisable and obvious, and yet mysteriously abstract too. Well done.

  2. I would never have guessed what this was! I like the colors and the geometric shapes created by slanting the photo. I don't normally care for slanted photos, but it really adds to this.
