Review: Fits my sink, sturdy, held a 1000/6000 stone just fine - Wanted to try hand sharpening, and already had a stone. Was originally just going to get a plastic or bamboo base, but read a lot of reviews recommending an over the sink one to have ease of access to water and cleanup, so tried this out. It has a lot of ton of adjustability, is long enough to bridge my sink, but sturdy enough that I don't feel a lot of flex when sharpening. Holds my stone securely, and didn't budge, even when sharpening a bigger blade like a chinese cleaver. I appreciate the locking bolts having a plastic knob rather than the metal wing nuts on other brands. Since it seems to just hold in place via tension/friction how it holds up long term is an open question, but as this would only get occasional use I'm hoping it'll hold up.
Review: Great addition - Makes sharpening multiple knives so much easier. Just set the sink to a slow drip and you have a constant flow of moisture for your wetstone and it won’t ever slide around and risk your hands getting cut

### ⭐⭐⭐⭐⭐ Great addition

### ⭐⭐⭐⭐ No tightening screws included.
*by A***R on January 26, 2024*

Seems like it is well-built, but the box came without the tightening screws so I can’t use it. 1 star for quality control. *EDIT: returned and ordered another. Came with the screws. Works great
