Hi guys,

I quite like the mechined finish on the grind you somtimes see on custom and factory made knives.
I have tryed 600gt belt on the grinding wheel but it dose not look as professional as I would like.
What am I doing wrong, do I need to look at the using the same grit on the buffing wheel.

Thanks in advance
jamie.

Yup.

Just discovered them, and I absolutely love them for satin finishes. The only thing to try to avoid, however, is touching anywhere you have a nice hard edge or line on your knife, because the scotchbrite belt will round them off quick as a wink!

You are right about the grind lines, it is very easy to wipe them out in a second.

If you carefully scotchbrite the hollow and then satin finish the flats you can keep the grind line pretty good.

A brand new new 320 grit belt also gives a nice finish. Sometimes I'll mirror polish the flats on a blade and go over the hollow grind with a new 320 belt. It makes a real nice contrast.

I believe the maroon is coarsest and they get finner the more you use them. I have the maroon and i am still using it after 2 years.

I'm pretty sure brown is coarse. I think maroon is medium.


Yup! Just checked on 3M's website.
