Expensive, but they work
"Very expensive, but very useful. I find this small size to be the most versatile -- stabilizing a whetstone, filleting a fish on a rock, opening a pesky jar, etc. Two small mats can be used for large cutting boards of different sizes/dimensions, and they're easy to clean. Stickiness reduces slightly over time, but not enough to significantly impact performance or usability. I begrudgingly recommend."
