Materials: plumbing snake (a cheap one 2 Dollars for 4 meters)
Tools: cheap dremel copy with cutting blade ( 14 Dollars)
cheap key file Set (2 Dollars)
sandpaper P240 and P400
most of the work was done with the dremel copy and then fine tuned with the files and sandpaper.
It takes me 2 houres to make one pick form start to finish.
