I use the original Lansky 3 stone set...
My first set, the stones just got so concave I bought a new set.
My second set needs replacement now... I do a few things...
1. I use good quality oil and have never had a stone quit cutting or clog up. I have had to glue a stone back in it's holder a time or two but that's no big deal for 10 plus years of use.
2. Once I set my rods in the stones, I never remove them. I built a box to store them in with the guide rods attached.
3. I am very particular about how I mount my knife in my holder. It is marked and mounted exactly the same every time.
4. I have a particular pattern for strokes per side and then flipping it over.
I also use my Lansky on a few other knives that see minimal use...
I hope this answers your question.
Have a blessed day...
