摘要： A hardness test indenter having a retangular base and four operative planeaces, a first pair of said faces meeting each other in a straight ridge with an included angle in the range from about 60.degree. to about 150.degree.; and a second pair of said faces making substantially equal angles with said straight ridge and so disposed in relation to one another and to said ridge that the first pair of faces have edges substantially symmetrically disposed in relation to said straight ridge; and said second pair of faces having between them an included angle in the range from about 60.degree. to about 150.degree.; the said straight ridge having a length not more than about 0.5 millimeter and not less than about 0.05 millimeter.
