A simple "C" shaped clamp made from lightweight alloy, the Super C Mount provides a simple, secure and stable way of mounting your Lansky sharpening kit to a table so that you can work safely with what will end up being very sharp knives. It's fairly substantial, seeming to be made out of cast aluminium, with a simple screw to hold the clamp in place. The mounting post can be attached in two directions to support either clamping on a regular, horizontal, table surface or a, sligfhtly more unusual, vertical surface. The mounting post is attached to the main clamp body using a small "grub" screw type fitting which , at first glance, seems slightly to short but in use shouldn't present any problems.
The actual post itself has a simple peg on the end which fits neatly into the Lansky sharpening vice. There are no screws, locks or fancy release mechanisms - just push the vice onto the peg and start working. While this doens't provide a fantastically secure fit, it is good enough for the reaonably light touch that's needed when sharpening and, on the plus-side, it means that flipping the knife over to sharpen the other side of the blade is no bother at all.
The Super C Clamp really does make a difference to the way you use your Lansky sharpening kit. It's such a difference that I'd think Lansky really should include it in the sharpening kit itself. Instead you've got to for out an additional lump of your hard-earned to get the best out of it. For that reason, it get 4 stars.
