Review on Efficient and Stable Sharpening with ASEL Whetstone Sharpener Non Slip by Brett Robinson

I have used this product several times in three months. I brought 3 knives back to life: a 7" chef's knife, a 5" chef's knife and a paring knife. They were 6 or 7 years old and had only been sharpened once or twice with one of those nifty sharpeners you stick a knife through. Don't buy any of them. Two chef's knives had grooves on the blade and with a lot of time and effort I was able to sharpen the blade to restore sharpness. I think if your knives were in as bad condition as mine I would buy an extra stone with a coarser grit to get the job done a little quicker. The stone has not shifted on my countertop during use. I am very impressed with this product and now my knives are very sharp.
