Assignment 26 - Sharpness

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!

Congratulations to the selected finalists. Remember in 3 days the votings will end and we'll have a winner!

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)...

damn, 2 images in and my knife and cactus ideas are already taken (I have some good sharp chef

Cut some cactus with one of your knives!

Yeah, I was thinking of that earlier today already. Certainly got enough to spare...

Plenty of room for improvement.......so these are just for fun...my attempts from today:

Nice concept Brant....


I am starting to think John should have included a safety disclaimer for this assignment.

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?

Not the greatest "shot" but here is my submission ...

No, I'm not a junkie or a diabetic. The needle is from when I had to give my dog daily allergy shots ...he will vouch for me that it is very sharp! Yes, the DNA is mine ...it's amazing what a person will do for an assignment!

Denise

Denise, that doesn't look like any fun; however, I like your enthusiasm. :)


How about fangs? They are pretty sharp!

I'll try with another bird picture...Not the best, but I think the blood on the beak accentuates the sharpness....

This is my first submittal on any website. I just started pursuing photography and thought these assignments will get the creative juices flowing.

<p sizset="0" sizcache="15"]Hi, this assignment made me remember a kind of strange period of tableware photography I had a couple of years ago. I went through the archives but didn't find anything I liked, so I took a new shot at it yesterday.
