METTLE was created with the intention of providing a bowl that functions on it’s own as a chillum.
Smokers like ourselves who prefer water pipes typically do so because of the additional smoothness you get from water filtration. This is why we engineered a few different options when iterating on METTLE, in an attempt to prevent any chance of Scooby snacks (ash) ruining your session or harshing your throat.
The chamber inside of the 14mm slide is 7mm around. This is why METTLE works perfectly with filter tips, just like what you’d roll up with. This is also why METTLE works so well as a portable finger saver for your roaches.
The 14mm slide is attached to the bowl, but we created a tapered hole on the inside. This allows you to insert any sized metal screen and lock it in place during assembly. Our advice is to seek high quality screens if you’re interested in adding filtration – there are many low-quality metal products still available on the market, and Kontra can’t speak to the quality of what you may find in a local shop.
You’re also welcome to place any sized glass or metal screen atop the bowl, as it widens from a normal size 10mm bowl to a massive 33mm around. This is probably easier, but your screens will last longer when placed underneath.
All in all METTLE can be reconfigured in multiple different ways with varying levels of added filtration to suit anyone’s taste.
