A little sharp but a took a little steel wool to it before I touched my guitar with it. Be advised. Ruler is cool, but not as unnecessary and useless as the 3 inch microfiber cloth. Less than 8 dollars. I can’t complain.

Could have been a bit stiffer/thicker and have better marking but it does the trick

Excellent tool for any aspiring luthier or anyone who likes to work on their own guitars. I got this to check the straightness of my new guitar neck and it was perfectly straight wouldn’t have known without this tool

The notched straight edge is great for the money! Very solid, and accurate. Great value! The string action ruler, however... isn't a selling point. It's completely useless! I still give 5 stars for the Straight edge.

The tool notches did not align with my 25.5" 21 fret guitar. Also as others have mentioned, it has some sharp edges.

This thing is dangerously sharp and like Someone else said it is bowed.I also used a granite plate and got it straight.It’s still on the sharp side but, I will keep working on that.For the price it’s great if you don’t mind spending a few hours fixing it.

OK
