I'm also looking at this model, it's more expensive but gets fantastic reviews so I may go with this.

Knife Sharpening / Re: How to achieve less than 1...

Sorry typo. Weekly ads. We get them from local stores in the mail. They are printed on thin newsprint. Sharp knives glide through smoothly. Use feel and hearing to detect any burr along the edge.

I am relieved, thanks for the clarification

I found this video on a YouTuber I follow and found it really interesting. I think I will invest in one.

That looks to be a good solution. Highly featured and good images. However, it is no longer available at the link below the video.  What is available is a larger screened one at $178. 

But, the one thing I took particular note of is the clear plastic shroud that he emphasizes.  Thumbs up.  That is precisely why I like the Kingmas hand microscope so much, maintains focus and the knife can be rotated, etc.  If it were available at the $60 price, I might be tempted. 

I'll watch his video reviewing the higher priced one to see if it has a similar shroud.  Without that, I think it would be a no go.

Thermal receipts and weekly ass printed on thin newsprint paper are also good indicators....

John, as a native English speaker I have no idea what "weekly ass" is    
I imagine it is lost on Andy and others whose first language is not English.
I am slightly intrigued but not sure I really want to know at the same time

...snip...
Might work, but a lot of bother to set up and occupy space, unless its already set up near your sharpening station.  It may also depend on what you are hoping to do, such as moving the knife bevel along to get a view of more than just a small portion.  I tried looking a knife bevel, but found at that magnification, it was difficult to keep the bevel in the picture - tiny movements are magnified along with the object. 

I have a setup for scanning (copying/digitizing) negatives, slides and prints using a Nikon D780 and a either a Nikkor 60mm or 105mm Macro lens.  Takes great photos, but I would much rather be using the hand microscope I posted about earlier.

That's a nice setup

Thanks.  In the world of digital camera scanning of negatives & slides, its relatively basic, but quite good enough for my needs.  Pipe stand, Manfroto Super Clamp, Benro 3-way geared tripod head, NISI focusing rail.  Even with all this, it is easy to have errant vibrations that can cause an image to be out of focus.  For instance, the floor in the room where it is, is not all that solid, and while my workbench is, even a little weight shift by me on the floor in front of it all can result in damaging vibrations.

Just to be clear, the image of the knife bevel was not shot with the digital camera. Rather it is what I see through the Kingmas hand microscope.  I don't have any images of knives taken with the digital camera because I just don't bother with it, the Kingmas is much easier and gives me the information I need.

If anyone is interested in more on close-up and macro photography, the absolute best references I've found are the two books by Lester Lefkowitz.  I have gotten rid of everything else.

I know it might be a bit of a pain but I am wondering how a tethered image from my 25MP Nikon D750 would look on my HD monitor. 25MP allows me to zoom in on details without loss of image quality. I have a nice macro lens that would work well.

One word of caution with the inexpensive USB microscopes is that most are not compatible with your phone last time I looked at them.

Image below shows what I can see and it is easy to travel along the whole length to see what the condition is.  There is a trick/learned process for maintaining focus that involves keeping the clear plastic base in contact with the knife the whole time and tipping the hand microscope to vary the focus point.  Takes up about the space of a cigarette lighter on the workbench.

That's a nice setup

Some also use cigarette papers to measure sharpness.
