Though made for artists, these palette knives are a blessing for woodworkers.
The mirror-finish blades taper from about 0.008" (twice the thickness of a human hair) at the tip to about 1/16" at the tang, perfect for cutting glue into fine cracks.
More flexible than a good drywall knife, they can be used to spread glue or remove it from your work, to apply and trim filler in restricted areas, or to paint in tight spaces where a brush would be too messy.
Usable in either hand, the forged stainless-steel blades are bedded in hardwood handles with brass ferrules, a rustproof combination.
Blades range from 1/2" to 1-1/2" wide.
