Introducing the Obsidian Flow Basalt Ledge — a fingerboard obstacle carved from real volcanic basalt, forged deep in the earth’s mantle and polished to an ultra-smooth finish.
This is not ceramic. Not laminate. This is authentic lava stone — the same material ancient civilizations used for temples, floors, and monuments that still stand today.
Every grind rings out with a crisp, glassy slide unique to polished basalt. Every trick feels locked-in, controlled, and unbelievably smooth.
Features:
-Premium volcanic basalt (lava stone)
-Polished volcanic surface → ultra–low friction
Basalt is harder than marble, more durable than concrete, and naturally smoother when polished.
It’s the closest thing to a “glass grind” you can put into a fingerboard park.
Dimensions:
Length: 8 inches
Height: 2 inches
Width: 2 inches
***DISCLAIMERS***
-The bottom portion of this obstacle is 3D-printed using high-quality PLA. While PLA is strong and durable for normal fingerboard use, avoid exposing the base to excessive heat (sunlight, car interiors, heaters) as PLA may soften or warp at high temperatures. This product is designed for indoor use only. Minor surface variations are normal due to the 3D-printing process and do not affect performance.
-The grind surface is crafted from real volcanic basalt (lava stone). As a natural material, each piece may display subtle variations in tone, micro-texture, or mineral patterning. These natural characteristics are normal and make every ledge one-of-a-kind. Basalt is extremely dense and durable, but the polished surface can still chip if dropped against hard surfaces. Handle with care and avoid impact to preserve the clean edges and smooth finish.
