The Wedge is a compact dab rig from GRAV: 4.75 inches of dense 3mm borosilicate cut into an angled body that sits in the palm. A curved downstem reaches deep into the chamber, so it runs on a low water line and pulls without splashback. It takes a 14mm female joint and costs $89.99.
Why the low water line matters
Most rigs need enough water to submerge a downstem properly, and getting that wrong is how you either choke the airflow or pull water into your mouth. The curved stem reaching deep into the chamber means a small pour is enough to seal it.
Less water between the banger and your mouth means less of the vapor scrubbed out on the way through. That is why a low line reads as more flavor rather than as less filtration, and it is the whole design argument for this shape.
The shape is doing work
Angling the body lets the chamber sit wide and shallow instead of tall and narrow, so the piece holds a usable water volume while staying flat enough to travel. At 4.75 inches tall with a 3.25-inch joint length, it is closer to a pocket piece than a desk piece.
The angled profile also fits the hand rather than demanding a grip. On a quick session where you are holding the rig and a torch at once, the shape is the feature.
Three millimeters of glass
Dense 3mm borosilicate is the wall-thickness spec, and on a rig this small it is the difference between a travel piece and a fragile one. Thin walls crack at the joint under the thermal swing of a torched banger going back onto cold glass. Thicker walls buy tolerance.

Who ends up reaching for it
This is for the dabber who wants filtration without a footprint, whose rig has to share a desk, go in a bag, or come out and go away again between sessions. It also suits people who dab quickly: no long chamber to clear and no stacked perc to work through, so the pull arrives immediately rather than building.
The trade is the one every small rig makes. Less glass means less cooling on a big dab, and the shallow chamber that makes it portable limits how much vapor it handles at once. This is a flavor-first piece built for smaller hits, not a session rig.
What it costs and where
It lists at $89.99 through HEMPER. For more diffusion in a similar footprint, the Rain Showerhead Rig runs a fixed eight-hole perc at 6.75 inches. The Globe Bubbler and the Wobble Bubbler are the other small takes in the catalog. More on the GRAV brand page. For adults 21 and over.
