Detailed description of the rectangle hook tool
The rectangle hook tool has the shape of a capital l, where the horizontal and vertical part of the character have the same length of 10 centimetres / approx. 4 inches.
The two parts enclose an angle of 90 degrees. They are equipped as a ruler with measurement indications in centimetres at the top surface and indents per half centimetre along the sides.
The body of the tool is two centimetres wide. On the outer side, near to the rounded corner and to the tips you find finger fitters for easy lifting or extra grip.
The corner between the sides is rounded at the outer side. At the top surface is a groove under an angle of 45 degrees for alignment.
The rulers are ending with a 90 degree hook serving as a pen blocker.
Pushpin markers are located near the rounded corner and near to the tips.
