the very tip part is steel.. the top im not sure the lower part and the metal bowl are soft aluminum and bends real easy but i am only concerned with the heat filter as i was inhaling smoke from it ,i torched the whole thing till glowing red when it had bubbled up, then i sanded it today and tried it.. seems to work the same and tastes better ive found that running the torch across the top tip thing works better then sucking or pointing the flame into it, i haven't removed the screen and i think its ok cause i torched the heck out of it too. i got a health stone glass bowl too and i use it as a vape by adding a screen inside it ,it's touchy to use but has a real clean flavor, you can read my review in the H.S. thread, these are over priced at 80 to 95 dollers but the glass is thick and ive dropped mine allot already, Also i tried to find a old style steel pipe for the metal VB at my local shop and they where all aluminum now probably made in korea i wish i would of saved mine when i first quit smokeing... i found a bowl from a cheap acrylic bong and it didn't smoke or have any finish on it vb should had left it a dull finish cause the upper area of the lower part gets hot enough to give of fumes from the chrome, im surprised the chrome stuff smokes and burns so easy you can place the vb on a stove burner on high for a while also to make sure everything's burned off. i think this is still the best pocket vape out right now some people don't have enough patience with my vapor genie this is easier to use for newbs
