Putting your blades under the USB microscope

Whilst researching low price USB digital microscopes, I found many forum posts asking about the suitability of these devices for assessing blade sharpness on knives and other cutting tools.

I ended up with the Digitech QC3247 1.3 Megapixel USB microscope which claims to go up to 400x zoom, purchased for $99 Australian over the counter.

For others interested in seeing how sharp their blades are at the microscopic level, the image above shows the somewhat shocking state of disrepair one of our Global knives is in, having been shoved in the drawer and dumped in the sink repeatedly. This was taken at the highest zoom I was able to get a focus with.
