Assignment 26 - Sharpness

[Sheiky]

For this assignment John (neuroanatomist) has selected the following subject: Sharpness!


Assignment description by John:


"No, not that kind (even though I don't mind staring at ISO 12233
charts!). The subject of this assignment is, literally, things that are
sharp. Subjects must have an edge or point that is able to cut or
pierce something. A few small examples below, one each from animal
(broad-winged hawk), vegetable (rose bush in the garden), and mineral
(Wüsthof bread knife)."





The following photos have been selected as favorites, it's now up to you to vote for the best!

Ok, I'll Start this one off with


Splitting hair (the blade is a Japanese Katana crafted between 1480 and 1500 and will still shave the hair on my arm)

I thought I was going to have to double-check the AFMA for all my lenses when I saw the subject, but I like your interpretation of sharpness, Neuro.

Good start, Bob. How big is that blade? Looks like it's sharp enough to cut your arm off, not just your hairs.

I'll try my luck with this prickly pear cactus from South Plaza island in the Galpagos.

I didn't want to go with the route of a macro shot for this assignment so how about a jet cutting through the air?

I'll build on the jet example and throw and arrow being shot through the air in here...

Adding another image to the cactus theme (thanks Andy)...

How big is that blade? Looks like it's sharp enough to cut your arm off, not just your hairs.

Andy, Its total length is 39 inches, exposed blade length is 27.5 inches and yes it would probably cut anything off of a human that you wanted to cut off---it probably already has

Safety Disclaimer? What's that?
