Hello! So here I am today, grinding away on my magic knots. It has been something liek 8 months since I have touched steel to abrasive, but I thought I was doing well. In fact, at a few points there I was doing fantastic, grinding my first Magic Knot knife with a 1" belt.

All of a sudden (as these things always happen all of a sudden like) the belt grabbed the blade and there was a brown burn mark in the steel! Unfortunately, the brown burn mark was on the other side as well.

I had other peoblems (blade bouncing up and down, I have to hand sand it now to make it perfectly flat, plunge is a bit hooey at the top, I ground it too thin, blah, blah, blah), but I am wondering if that burn mark means that the blade is junk? I sure hope not! I humbly place myself before the experts, and await your guidance

P.S., This has proven to me that I am destined to forge, or that I need to quit University and do nothing but grinding to get better!

stuck two of my knuckles into a 50 grit disc yesterday.....we learn nothing by doing it correctly....everything by our mistakes.. (famous quote by me!!)
 
The brown streek may have not hurt it. Do the brass rod test in that area to tell. You may have been useing an old belt to get it that hot? Bruce B
 
Thanks for the info!

Bruce: I forgot to mention that the blank isn't heat treated yet.

I don't know what was the cause of the problem. I used a fresh belt to grind. I think I just lost my attention for a second. That is all it takes.

If it is soft (pre heat treating) don't worry about it. The brown should have disapeared with the next pass of the belt (assuming it cooled down). If your belt is grabbing and pulling the blade down, your belt is dull or needs to be cleaned.

Days like that, just turn off the lights and read a book. Its not worth risking injury during a bad day.

Hey, I've got a solution. Drill a hole right where the spot is and say you did it to lighten the knife. Hey, Mr. Mayo, is that what you do

I agree,Since you haven't had it heat treated yet you are good to go with no problems....
I also agree with,when having a bad day it's time to shut off the lights and go to the house.

I did stay out there to get rid of the brown mark, and then I packed 'er in. My grind isn't totally flat and maybe I was getting frustrated at that and then the little slip happened! I dunno. I'll leave it be for a while and go back later.
