That is a neat toy for sure.
" quality ones are expensive and you need a precise stand to hold the knife steady esp. at higher magnification. Even then, focusing is a challenge as the knife is not flat so just some of the field-of-view (FOV) is focused and that assuming the glass has no distortion. Add to that the challenges of photographing it and getting the light right and color correct and polarizing to reduce reflection, etc. Ken details some of the challenges in this post: post137574.html#p137574
Practically speaking, a quality 7-10x loupe is really all you need to use while sharpening. There really is no substitute for good glass either. Beyond 10x it is difficult to hold steady and the FOV is reduced.
IF you are curious a small pocket microscope
@60x will give you a very closeup view. I have one and for $14 is worth getting (recommended
) but using a loupe is better suited to sharpening IMO.
The image below is a 15x view of an edge taken through a loupe with iPhone 5s.
What does the image tell you?
The image is of a Gassan blue #2 steel edge sharpened to a 15k Shapton then finished on a Hakka natural stone. To the naked eye the edge is a shiny mirror reflected in the sun with enough tooth to bite tomatoes or peppers skins without sliding, a very fine edge indeed, the complex edge off a natural (compare with the previous Shapton images
