METTLE is the most functional smoker’s tool on the market. It’s an indestructible, universal bowl, that functions with a built-in screen, functional chillum, and roach holder/finger saver. 

It fits any downstem and slide, 14mm male, 14mm female, and 18mm male. 

METTLE is compatible with 7mm tips, allowing for additional filtration as needed, however the 4-hole design already allows for great airflow while preventing excess debris from entering into your water chamber. 

The outer slide of METTLE is removable, allowing for its use as an independent 14mm to 18mm glass adapter. 

METTLE is also incredibly easy to clean. Simply remove the bowl, and wipe out the usually hard-to-reach underside of the bowl. 

 Made of thick Stainless-Steel, METTLE can be the best and last replacement bowl you ever buy. 

Kontra is a small team in Nashville, TN. Our Mission is to modernize smokeware in both design and function. 

There are no other products that you purchase with the expectation that they break, so why it acceptable for our bowls? We don’t believe smokers should have to buy multiple bowls every year due to breaks and inconsistent craftsmanship. Our bowls are machined, ensuring consistency in every bowl.
