Knife Sharpening Angle Guide for 1 x 30 Belt Sander

Hay que ajustarlo con un inclinómetro, pero funciona bien como respaldo

You have to fine tune this if you’re going to be using it a lot for knife sharpening. The angles marked aren’t even close so disregard. Alexandria sharpening on u tube has an excellent video on what needs to be done to fine tune this little gauge. Works as advertised but not accurate until it’s modified

This is easy to use, and works well. They also sell a set where one is reversed to you can do 'toward' or 'away' from the blade. It's kind of crunchy which can make adjustment touchy. I took it apart and used a fingernail sanding file to smooth the surfaces. I even took the nuts off and smoothed the surfaces. Any place metal moves and rubs I make sure there were no 'nubs' and now it's like a high priced precision tool

Pointless product,do better freehand.

It works well but it takes a little time and practice to learn to use it well.
