Materials:
masking tape
2 RSVP grips
2 pencils
the nice thing that i found about this mod is that it can be done with a variation of grips and u can find the materials almost anywhere.
dont no if it has been done before but I took a normal staples brand pencil (can be found anywhere) (unsharpened) and attached the eraser of the second pencil to the unsharpened writing end of the first. this ballenced the pencil. then i wrapped 1 layer of masking tape over the seems of the eraser-barrel and took 2 grips from Pentel RSVP pens and put them over the masking tape. this made a perfectly balenced and nice looking pencil for spinning. It is also a decent wieght and length and width.
