I've had a Lansky sharpening set for about 20 years and have had trouble holding the blade clamp when sharpening knives. I don't know why it took me so long to make this purchase, but I'm glad I finally did! The clip is very strong and holds the blade clip very well. The screw on the base fits either side, allowing you to attach it in two different ways. It appears to be very well built and the blade clip fits snugly into the base. I can set it up on a kitchen counter or even just a portable table and sharpen my knives while I watch TV. I would say this is a must when buying a Lansky kit. Overall I am very happy with the clip and would recommend it to anyone who owns or is planning to buy a Lansky sharpening set.
