The stroke adjustment of the Classic AirGraver® makes the tool perform like numerous handpieces in one.
The Classic AirGraver's length of stroke adjustment provides a virtual multitude of handpieces in one tool. At any given
stroke length setting (determined by the adjustment ring on the barrel of the tool), the power is varied with air pressure from the foot control or
PalmControl®
(.05psi to 80psi). The absence of an internal spring means uniform performance throughout the range, with no “sweet spots” or “dead spots”. The full range of
power and speed is "sweet" throughout, due to the internal automatic balancing of air pressure on both the impact and return strokes.
An advantage to the AirGraver® design is the speed at which it can move a graver physically through
the metal when desired. The throttle range is possible because the tool's speed and power work together. If the tool would only increase in power but not
with speed, the result will be more broken points and staggered stair cut marks in the cuts. Increasing impact speed and power together will deliver an
improved, wide range of throttle speeds. An experienced engraver can increase their productivity significantly.
The AirGraver's delicate impacts gives the user ideal control. The
AirGraver® system requires air consumption of 0.1 to 0.3 CFM at full throttle, allowing the use
of smaller air compressors.

Rapid Graver Change
The Rapid Change of the Classic does not utilize inserts or attachments, simply slip a 3/32" graver into an handpiece and it is ready to go. The graver
can also be locked down with using a setscrew or thumb screw if desired.

The inset in the
butt of the custom burl wood and ivory handles is a banknote style
engraving, designed for the tool and reproduced with a restored 1915 150
ton coining press. The design was engraved in tool steel, hardened, and
used to reproduced itself in the press.
