A fair bit longer (352mm vs. 251mm) than the #4 smoothing plane but still with the same 51mm-wide blade. Its blade can be honed square for jointing (straightening) work on smaller work pieces or sharpened with a camber for smoothing and flattening stock. The sole of this version measures 352 x 62mm. For replacement parts - see the listing for common components. Stanley's perfect design with Luban Planes' famed quality and reliability The design of these high-performance bench planes are based on the famous Stanley Bedrock series (regarded as one of the very best designs of all time) with a fully machined frog and body seating pad. The Bedrock design ensures the blade is held with absolute rigidity thereby preventing chatter. The sole of the planes are heavy, stress-relieved ductile iron castings that are machined and lapped smooth to tight tolerances so little tuning needs to be done to get them working immediately. Superior linishing across all Luban Planes makes the difference. Linishing is the term given to the belt-sanding process that ensures all plane surfaces are flat, dressing the plane surface before selling. If linishing marks are deep, which they are on so many of Luban&rsquos competitors, then the plane surface simply isn&rsquot
