It is easier to get a good streak that way rather than holding the slide flat. Please move your question to microbiology.
So that only the edge touches and you are able to get a clean, even drag.
To prevent contamination.
To accurately cut a miter at a 45-degree angle, use a miter saw or a miter box with a handsaw. Set the saw to a 45-degree angle, place the material against the saw fence, and make the cut. Ensure the material is securely held in place to maintain accuracy.
Microscope slides are held in place on the microscope's stage by slide clips or slide clamps.

A microscope slide should be held by its edges to avoid leaving fingerprints or oils from the skin on the slide surface, which can interfere with the clarity of the image under the microscope. Handling the slide by its edges also helps prevent accidental damage or smudging of the sample on the slide.
Fist at arms length = ~ 10 arc degrees Thumb at arms length = ~ 2 arc degrees Little finger ~ 1 arc degree
A microscope slide and coverslip should be held by their edges due to leaving fingerprints and/or debris and how easily breakable they are. Leaving fingerprints or debris on either a slide of coverslip will alter the view under the microscope.
Slide, Inc, was founded in 2004, is privately held. So, no ticker symbol is available as of now.
Footballs are not kicked from a perfect 90 degree angle during a football game on either the kickoff or for a field goal or extra-point. Whether from a tee or being held, a football is leaned back slightly off 90 degrees toward the direction of the kicker. This placement allows greater distance and accuracy.
A Dutch Angle is when a camera shot is take while the camera is held at an angle. Rather than vertical lines appearing in parallel to the edges of the picture, they appear at an angle.
