Precision manufactured from 6061 billet aluminum and heat treated alloy steel, the Shark is a conservative pneumatic tool using only 5 to 8 cfm @ 2250 BPM.

One time, the inventor laid the Shark down too heavily onto a beautifully finished slab and mucked the whole thing up.

Lesson learned, he strategically placed No-Mar plastic cushions on the tool because even cautious operators can lay a tool down too hard and damage a decorative concrete finish.

The Shark Weighs 14 pounds.

This in-between concrete engraver is great for cutting designs with fine detail. It has a specifically designed head that can cut into most small apertures.

The Barracuda Concrete Engraver has 19 replaceable impactors.

The Barracuda weighs 6 pounds.

When it comes to touching up, removing islands, smoothing voids or adding extra detail to engraved patterns, the Mini-Mocton Stylus Wasp Concrete Engraver is a handy pneumatic tool.

The Wasp's name comes from the sound it makes while it works.

It has a single reciprocating carbide stylus cutter called the "Stinger."
