Pretend you are a teacher preparing a quiz for the text I will provide. 
            Each quiz question should follow the format below. 
            Ensure that you carefully recheck the questions and answers for accuracy. 
            The output should be a ready-to-use list of dictionaries for the Python eval function:

3. Hatchet: - also called enamel hatchet. The cutting edge of the hatchet is parallel 
to the long axis of the handle and beveled only from one side (Fig. 3A). It is used 
for cutting enamel and dentin and comes as right or left types for using on opposite 
sides of the preparation.  
4. Gingival margin trimmer: - This instrument is used for beveling of the gingival 
enamel margin of proximo-occlusal preparations. Also it is used for beveling of 
axiopulpal line angle of two surface preparation as in class II cavities. It is similar in 
design to the hatchet, except the blade is curved, and cutting edge is at an angle 
(other than parallel) to the long axis of the blade (Fig.3, B and C). It is made as right 
and left types. Also it is made either a mesial pair or a distal pair. When the second 
number in the formula it 90 to 100, the pair is used on the distal gingival margin. 
When this number is 75 to 85, the pair is used to bevel the mesial margin.

5. Spoon excavator: - The blade is curved and the cutting edge at the end of the blade 
is in the form of a semicircle. This gives the instrument an outer convexity and inner 
concaving that makes it looks like a spoon Fig. (4). Like the hatchet the cutting edge 
at the end of the blade is parallel to the handle, therefore there are left cutting and 
right cutting spoons. The shank of some spoons holds a small circular (disk blade) 
or claw – like blade at its end. The disk blade is known as a discoid, where the claw 
- like blade is termed a cleoid (Fig 4, A and B).

Instrument Formula Given by G.V.Black: 
 3 Number instrument formula: Cutting edge of the Instrument is at a right angle to 
the blade. 
 a. First number- Width of the blade in tenths of a millimeter. 
 b. Second number - Length of the blade in millimeter.  
c. Third number - Angle the blade forms with the axis of the handle in centigrade. 
Example: Enamel hatchet. Fig 5

4 Number instrument formula: Cutting edge of the instrument is at an angle other 
than a right angle to the blade. a. First number - Width of the blade in tenths of a 
millimeter. b. Second number - Angle the cutting edge forms with the axis of the 
handle in centigrade. c. Third number - Length of the blade in millimeter. d. Fourth 
number - Angle the blade forms with the axis of the handle in centigrade. Example: 
Gingival marginal trimmer & angle former. Fig 3.
