Suitable for making sections with a thickness of 25-200 nm.
Since the cutting edge is protruding, it is easy to bite into the sample, and it reduces the compression of the section during cutting most among knives other than ultrasonic.

A diamond knife with a blade angle of 25 ° is used on the front side (about 2/3 of the left side), and a diamond knife with a blade angle of 45 ° is used on the right side of the remaining 1/3.
The exposed part at 25 ° allows a clear cross-sectional observation of the subgrain structure, but it is completely unclear at 45 °.
The difference in compression due to the difference in blade angle is clear.
