NortonSaint Gobain Abrasives 61463686839 Hard Translucent Arkansas Abrasive File Set, 1 Each of Ultra Fine Arkansas: Square HF13, Triangle HF113, Round HF813 & Sharp Edge Knife Blade HF873 (Set of 4)

Great little set for polishing triggers. I wish there was a half round included but this set will cover most anything. The price is great compared to other online retailers as well.

Some of the best stones I have ever used.

These stones do a very nice job at machining, grinding down and polishing.The main reason I knocked a star off was for the lack of description about the stones themselves and ALL the design features. I needed at least one square stone with sharp right angles on the long edges, and the square stone DOES NOT have that. They do however have right angles on the 1/4" short edges which still allowed me to do one of the things I needed them to do, but it wasn't idealOtherwise, these stones where packaged and shipped with extreme car and made it safe and sound

These four stones are great for defiling and sharpening edges in tight spaces also left my knife extraordinarily sharp

Ok.

I was really excited to get this multi-shaped Norton translucent stones kit to sharpen my wood carving tools such as V-tools, Gouges, Spoon/and Bowl carving tools which this kit is really handy except for one thing and one thing only and that is the size of the kit that is so minute, micro, which hardly can fit my tools. Unfortunately, I'll have to return it as this kit is too small for the size of my tools.

I bought the stones to hone metal parts. Their tiny size makes me fear they will break in use.I don’t fault the vendor in this. They were prompt and got the product out to me on time.I fault Norton for putting out this diminutive product.
