The Robert Sorby Timber Framing Slick (model 289) is a heavy Sheffield slick for timber framers and boat builders, in 1-7/8, 2-3/8 and 3-3/8 in widths, with a replacement handle sold separately.

It is a strong, solid one-piece forging in high carbon steel, with a heavy-duty tang and a socket between blade and handle for strength. The blade is offset from the handle for clearance in deep mortises, the working face is ground slightly hollow to make honing easier, and the back is rounded to take off the sharp corners. The blade is 10 in long and the slick about 27 in overall, on a contoured ash handle. Use it for deep mortises and long paring cuts; like all slicks, it is pushed, never struck. Sorby's leather edge guards and holsters fit the 2-3/8 and 3-3/8 in.

Robert Sorby & Sons was first registered on Union Street in Sheffield in 1828, and the company still makes its tools in the city. Sorby traces the family's roots in the Sheffield trade back to the 1600s: Robert Soreby was the first Master Cutler when the Company of Cutlers was formed in 1624.
