About Obsidian
We're not a vendor.
We're the shop
behind your shop.
Owner-operated, built from the ground up to serve the people who actually build things. We know what it costs you when a job stalls because a blade didn't show up or an adhesive didn't hold.
Most shops can't justify a full-time purchasing manager, a tooling specialist, or a safety coordinator. We fill those gaps — carry the inventory, vet the products, stay on top of what's new.

How We Simplify
Three pads instead of seven.
The Sierra and Mantis hybrid systems replace a 7-step sequence with three. Same finish, fewer changes, less time on the machine.
Aggressive
Takes stock. Removes saw and grinding marks on tumbled travertine and rough edges.
Sand
Levels the material and clears what the 0 pad left behind.
Hone
Semi-gloss, smooth to the hand. Where most shops stop on honed tops.
Polish
Full gloss. Run a fine or medium cup wheel first and the set lasts longer.
