VERITAS Iron Edge-Trimming Block Plane
If you have already purchased the right-hand model, you may want to consider its complement. Having both models will let you handle any grain direction.
The depth-adjustment mechanism is a large thumb wheel and an independent traveller, resulting in fast and accurate depth setting with no blade skewing.
Set screws along the side prevent the blade from shifting when knots are encountered.
The edge plane can be used to make controlled bevels, such as required for
boatbuilding. Simply fasten a wooden wedge to the plane using two wood
screws (not included) through the holes machined in the plane body.
