The second blade 24 is bent at a right angle on a wide surface 38 of the shank 20. The blades 22, 24 extend at right angles to each other from the shank 20. The ends 32, 34 of the blades 22, 24 are in a contraposition to each other.
In Figure 5, the first blade 22 is bent at a right angle on a wide surface 38 of the shank 20.
The first blade 22 has a one quarter turn twist at 40. The second blade 24 is bent at a right angle on a wide surface 38 of the shank 20 in an opposite -direction to the first blade 22. The ends 32, 34 of the blades 22, 24 are in a contraposition to each other.
In Figure 6, the first blade 22 is bent at a right angle on a narrow surface 36 of the shank 20.
The second blade 24 is bent at a right angle on a wide surface 38 of the shank 20. The shank 20 has a one quarter turn twist at 42. The blades 22, 24 extend in opposite directions to each other and the ends 32, 34 of the blades 22, 24 are in a contraposition to each other.
- In Figure 7, the first blade 22 is bent at a right angle to the shank 20 with the end 32 of the first blade 22 flattened transversely to the shank 20. The second blade 24 is bent at a right angle to the shank 20 in an opposite direction to the first blade 22 with the end 34 of the second blade 24 flattened parallel to the shank 20. The ends 32, 34 of the blades 22, 24 are in a contraposition to each other.
The overall length "A" of the wrench 10 is typically seven and a half inches. The overall length "B" of each blade 22, 24 is typically one and seven eights inches. The size of the rectangular cross section of the flat steel bar 28 is typically one quarter of an inch in width "C" by one half of an inch in depth "D".
The diameter "E" of the cylindrical steel rod 30 is typically between three eights of an inch to seven sixteenths of an inch. The overall length "F" of each blade 22, 24 in Figure 7 is typically two and one eighth inches. The size of the rectangular cross section of each flattened end 32, 34 of each blade 22, 24 is typically one quarter of an inch in -width "G" by one half of an inch in depth "H".
