i think hemp trumps cardboard, only cuz you can soak it in resin and then smoke your pants ha ok seriousely, i think hemp would be the more resin stick over cardboard.


just the natural logic of the matter.


as for scraping...


flat head screw drivers for most of it, depending on the paraphanilia, a swiss army knife is good, as long as the blade fits the piece you are scraping, then switch back to screwdrivers for the mouth piece and bowel stem.
it's also good to scrape your scraping utinsils lol
and a philips screwdriver is OKAY, as long as you have something to scrape the screwdriver with, like a saftey pin. philips' work for the mouth piece and interconnecting stems (depends on the pipe).

as for glass pipes... i have no experiance really, i assume it'd be good to dry boil them.

kinda like how you make hot fudge... lol


home made bongs, like my dad's, are easy and quite bountiful.

we use a gatoraide propell bottle, and when it turns black (from blue haha) we cut 'er open and let her dry out, while i scrape the stem and bowel.

it's a nice stem and bowel, could be used as a straight shooter if it werent for the melted plastic and tape all over the outside of it... and water resin on top of that, cant scrape the outside unfortunately... but the inside is almost ALWAYS FULL of black gold


and since there's no screen, once the bong dries out, you get some HEAVY shit in the end, this stuff can trump REAL pot

i think i will call it bong hash
