Most Helpful Positive Review Excellent Product
I have had the Triangle Knife Sharpening System for about 40 years. I bought the first one at a gun show in Houston. I was replacing the stones on my last order. I have used virtually nothing else for forty years. You can sharpen scissors, serrated blades, etc. It is the best system I have ever seen. I have been recommending this system for 40 years! Pros: The best sharpening system I have ever found and I have sharpening knives for half a century. Yep I'm old! Cons: If you drop the stones or your cat knocks it off the stones will break! ;-)

versatile sharpener

by Bob, Verified Owner from AR, United States Written on November 18, 2025
I like the Spyderco ceramic rods , tougher than normal round rods. You can use the flats or the edges depending on the aggresion you want. I went with fine and ultra fine and combination makes a razor sharp edge with good polish on good steel.

Nice stone

by Hunter, Verified Owner from IL, United States Written on November 8, 2020
This is a great stone to add to your spyderco sharpermaker system. If you want a sharper and cleaner edge on your knives the ultra fine stone is a must buy. This stone is great for serrated knives as well

Get the sharpest knife

by Legacy Reviewer, Verified Owner Written on April 29, 2013
Brings your sharpening game to the next level. When I want to get a mirror finish on a knife, I work my way up to these then complete it with a few swipes on a leather strop. Don't forget that you only get one of these stones per order, so you might want to get two.
Pros: sharpens like crazy
Cons: Only comes with one stone at a time
Would recommend: Yes
