A friend of ours suffers from arthritis, making it difficult for her to use her Lansky knife clamp hand-held to sharpen knives. Lansky makes various mounts, such as the “Universal Mount”, but these were not readily available in the rural village where we live. I made a stand, using a section of 25 x 25 square tubing for the post (Photo 1). Four holes for the mounting screws were first drilled and countersunk, about 15 mm from one end of the square tubing (“A” in Photo 2). The tubing was then split along the corners, bent outwards 90 degrees and the sharp edges smoothed (“B” in Photo 2). A small flat was filed on one corner and an M8 nut welded to the post (“C” in Photo 2). A piece of 8 mm rod was welded to a section of threaded rod to form a T-handle for the clamping screw (“D” in Photo 2). A length of 16 x 3 mm flat bar serves to hold the Lansky knife clamp in position diagonally across the square tubing post (Photo 3). The flat bar was bent more or less into an elongated “S” shape as per Figure 1 and spot welded inside the bottom of the post. Only very light pressure is required to hold the Lansky knife clamp firmly in position. About a quarter turn is needed to release the clamp when inverting it to sharpen the other side of the knife blade. The assembly was screwed to a wooden base and rubber pads were affixed to the bottom of the base. The stand can be held down by hand on a work surface or, as in the case of our friend, clamped to her granite countertop in the kitchen using quick-release trigger clamps.
