One step beyond a high angle smoothing plane, scraping planes take a very light cut and produce a clean surface with no concerns about grain direction and no tear-out.
The blade is sharpened square or very lightly cambered at 45°, then a hook is burnished that does the cutting. Depth of cut is set fine tuned by leaning the blade forward or back via the opposed thumbwheels. Sole dimensions: 238mm x 88mm.
Blade: 1.6mm thick 73mm, from T10 carbon steel hardened to RC59.
