How do you all photograph edges or magnify a knife edge. Ive looked at ordering up everything from a jewelers loupe to a USB microscope with LED illumination
I just want to be able to see in more detail than a 3+ reading glass the edge condition before and after. Any thoughts?
 
You'll want more than 10x to see the edge well. For pictures I think one of the most popular is the Veho 400, I think they go for around $50.
 
Bought a basic triplet 10x jewlers loupe for around $10 or a little less than that when all was said and done a couple years ago, nothing fancy but it works and it shows what is going on. Pair it up with a sharpie and your in business, personally I prefer a red sharpie as it just seems to be easier to spot than a normal black sharpie. And some paper to slice to see if it hangs up anywhere and to check to make sure it cuts cleanly and your doing pretty good in supplies to check your edges. And you can do the 3 finger sticky if you choose to do so, I know I do it as it helps me verify it's fully apexed and finding other defects before I move onto the other methods mentioned.

My method as well. 10X does what I need.
 
I've compared dinolite and the veho and there is no comparison in quality... Its hands down dinolite for me!

I'd stick with a loupe at 12-20x. The higher magnification you go, the smaller your field will be and the darker the image. Unless for cosmetic reasons I wouldn't bother with a microscope - all the important stuff you can see with a <20x loupe, and images at medium magnification can be misleading. You won't get a real look at the edge with anything under 400x optical (IMHO) and that's the bare start point.

Is there a preference for jeweler loupes over a magnifying glass? I've seen a lot of discussion of loupes but not much on magnifying glasses.

My preference, mostly because its all I've ever used, is graphic arts magnifiers. They usually come with a stationary base for looking at printed or photographic material, but the magnifier can be unscrewed and used like a jewelers loupe. The issue with jewelers loupes is they tend to be real small. The ones we use at work tend to get knocked around, fall off of desks etc, we order new ones every couple of years.

and the "AM 14" from this location.

Awesome advice. I got a 10 and 20x triplet from a jewelry company. They work awesomely. I also got a Carson Flex microscope. That was cool and I can show my clients exactly what the edge looks like.
