They shouldn't make grinders out of aluminum to begin with imho. Even if they are CNCed.
I would rather use a plastic storz & bickel grinder any day over a aluminum grinder. But a titanium grinder I might want if I could be assured it was manufactured to extremely tight tolerances so there is no rubbing.
TommyDreamerPlastic grinders are molded. If anything, having flakes of plastic that melt during combustion or vaporizing is far worse than aluminum flakes that do not melt nor even likely get produced due to the high tolerance levels. Mind you, this grinder is overpriced and there are far cheaper, comparable grinders on the market, made of 7075 aluminum.
BogartThese aren't actually machined out of titanium, it's just a marketing gimmick. It says right in the description that they're machined out of aluminum with "a titanium finish". Maybe they have a nitrite layer applied, maybe it's just the color.
But to be honest, I don't really like that they reference titanium in such a way that it appears as though it's machined out of titanium. It isn't. Titanium is extremely difficult to machine because it's such a hard material, and it's incredibly expensive to make anything out of it a result of that challenge and the cost of the raw material.
If you have a SpaceCase already, don't bother. There's zero additional benefit to this model
I just read the link Tommy posted - this isn't something you need to worry about with grinders! You would need to atomize a HUGE amount of aluminum to have any issues. So don't worry; just use the one you have and enjoy it.
spiznasIf something is not properly CNC'ed it can scrape (titanium) aluminum metals into your product thus making you smoke it... I think tommy worries a bit much but it is possible. I have pulled product out of my machines before with conflicting edges and flakes.
MeowmixingYes they are (S&B grinder) molded, and yes inhaling plastic is not healthy either.
However molding plastics can allow for higher tolerances than a CNC machine from what I've read. So there is a much lower chance that the plastic will actually ever touch, and since the plastic is much harder than the dried plant there is little chance any of it will rub off.
The only area metal seems to be better is in sharpness, so it handles stems better. I have had a couple metal grinders and even the ones CNCed from solid aluminum have rubbed at the blades, you can see the finish come off over time.
I actually got very sick from the first grinder i had, because the paint ended up coming off when I cleaned it w/ alcohol. Subsequent grinds made me sick to the point I vomited.
It sounds like Space Case is a much better brand then what I bought, despite actually costing less. But I want to avoid aluminum if at all possible because of all the negative health affects & the one's it's also suspected in (like Alzheimer disease).
I wish a company would actually create a real 100% titanium case. Even if it was $200, I would still buy it. There are so many Titanium cookware companies out there that make camping gear. A grinder shouldn't be too hard to make. If it was forged that would be a BIFL (buy it for life) quality item.
McLovinI don't have a space case. The black case I had where the paint came of when i washed it & used it was made by EB (elwoodbrooks.com). I knew almost nothing about grinders, it was just the one the guy at the shop told me was "the best". Obviously a lie. My guess is, it's the one he makes the largest profit on.
Considering all the extremely toxic & carcinogenic things that are in paint, especially black paint, I threw it away. The shop had the audacity to tell me they don't accept returns on used merchandise. They're lucky I didn't sue.
I would like a high quality grinder, but I don't want another one where the paint is going to rinse off w/ alcohol or chip or the blades rub. Especially if it's aluminum.
It's nice to save money, but price isn't that important to me. The way I see it, it's an investment in my health.
TheDylanGood input TheDylan. That's what I had heard from someone else as well, and it would explain why grinder's I've had before have actually rubbed.
Do you think a forged grinder would have tighter tolerances?
spiznasIf you're talking about aluminum cans that soda comes in, those cars are coated with a plastic resin inside so the drink never touches aluminum. If it did the acid & carbonation would eat at it and you would get sick pretty fast drinking them.
Some frying pans are made out of aluminum you are right (because it's cheap and conducts heat well), but the industry is moving away from that because of all the science showing it's dangers. Most modern cookware is coated with a ceramic or stainless steel.
