Quite sharp, says John

I noticed that it was the day for a Tiny Tuesday challenge, and on checking, saw that the theme was to be 'sharp'.

Since I am working with John, and I had explained the notion of the Blip challenges to him, he kindly went to his workshop and brought me one of his chisels. He is a fine woodworker, turning his hand to virtually anything, and he also knows a bit about metals. It could also be said he knows a thing or two about photography and he had been explaining about 'diffraction limited resolution'. I'm not sure whether I've got it yet, but I'm trying.

I put his chisel onto a jug in the kitchen window and popped off a few hand-held shots at varied settings to check on the resolution!
