Thanks for reviewing my design. I do really appreciate it. Here is a new proposal for your consideration (#68, #69 & #70).
The basic idea is the tip of a pen/pencil that represented by three triangular shape which leads to the upper right. At the same time, it also form the folds of paper that you can see on the negative space at the center of the symbol.
Please let me know if you have any question or request on this design concept.
