Clamps
We work with wood at a
workbench
or
table
.
Carpenter’s pencil
: Oval
shaped to avoid slipping
on the wood. The lead
is strong so you can use
it on different surfaces
(stone, wood, paper or
cardboard). You sharpen it
with a special knife.
Awl or punch
: Used to
make a small mark in the
wood so you know where
to drill a hole.
Compass

circles and arcs and
transfer measurements.
Marking gauge
: Used to
draw lines parallel to the
edge of the board.
