while using my metal pipe i wait til its pretty resined up inside the mouth piece and took it apart and packed it with weed then once i could see the weed on both ends i took 2 pencils(unsharpened) and pressed it together on each end, then took 1 pencil to push it all out the weed was rounded and was quite sticky with resin... i then took a knife and cut the long rounded weed into small chunks and did blades with them... works good
