## Customer Reviews

### ⭐⭐⭐⭐⭐ Saw Blade Sharpener
*by M***E on March 18, 2025*

Worked as expected.

### ⭐⭐⭐⭐⭐ 320 grit - Very good for tungsten sharpening
*by P***E on April 8, 2025*

I simply use this a speedy way to prep tungsten electrodes - the 320 grit is just right.

### ⭐⭐⭐⭐⭐ Use it to sharpen tungsten
*by S***0 on September 2, 2023*

I got this to sharpen my tungsten on my tig welder. I am not a good tig welder yet so I am constantly buggering up my tungsten. Works great so far. Have ground a full tungsten stick to almost gone 1/4” at a time. Disc seems to be holding up, no signs of wear.It would be nice if the edge had diamonds, it is smooth so when I really get globbed up I have to grind it square all the way past the contamination which is slow. No side cutters to score and snap but it sharpens very nice on the 320 grit
