Okay, thanks for the responses to date as of 6 Oct, 7 AM PST. Nevermind the microscope then. What loupe or magnification tool do you use to see the burr or edge? Someone said they use a variety of loupes, what magnifications should I be looking at? Specific models would be appreciated.

If it matters, I can't focus up close with just my eyes. I have artificial lens from cataract surgery. I can see well enough from a foot to far away.

Hi, my first post here. Suddenly got the bug to learn about sharpening. I have several books and DVD on their way to me. DVD's by Murray Carter, The Razor Edge Book of Sharpening by John Juranitch, Kife Sharpening Made Easy by Stefan Steigerwald and Sharpening Made Easy by Steve Bottorff.

I've hear about burrs and I'd like to see for myself what this looks like. I understand you can feel for this but how can I feel if I haven't experienced it yet. In any case, i think it would be a good thing to be able to look up close. I started googling for microscopes then it occur to me to come here and ask people who know.

So my question again is: for those who use one, what microscope do you use to look at the knife edge and burr?

Thanks in advance for your help.

I have used a microscope, at work. It is a stereo scope. I no longer use it as it will drive you crazy...it did me. You will not be satisfied until you remove every blemish and depending on the magnification you will always see a "rough" edge.
I use a 15x loupe and find that just right.
 
I use a bunch of loupes from 12-15x. Is perfect for inspection and burr removal.

I would be leery of buying a microscope for close inspection unless it be very high powered. It is easy to misinterpret what one is seeing at moderate magnification if one is trying to determine true edge effects instead of cosmetics/macro effects - have read a number of conclusions from individuals using mid-range microscopes that do not hold up at higher magnification, are nothing more than assumptions based on incomplete information. I try to be very conservative with my own conclusions and that at 1000x.

FWIW, I have yet to catch any burrs at higher magnification that were not visible with the 12x loupe. The human eye can see a candle at night from several miles (or more). With strong overhead single source lighting, is possible to light burrs up and be nearly 100% certain of their presence or lack thereof using just the naked eye (and some practice).

True - that beautiful edge looks like rough terrain under a microscope. Loupe is the way.
