Not hard technically, but hard to do cheaply. There used to be a LOT of American manufacturers of pencils, but they've all been wiped out by foreign competition.
Interestingly, Dixon's pencils are actually made from American lumber. They just find it cheaper to 1) ship those wood across the ocean, 2) get them made abroad, into pencils and 3) ship them back to the USA as pencils, rather than having pencils made domestically.
