Dear all,

May be you dont remember me, I had been asking some questions some months ago. After some time off the forums and some knives later, I would like to share with you all, some things:
1. Question: when you grind a chute knife which part do you grind first? the top or the bottom? Because I made one, but I kept correcting the lines up and down and is a bit @@#*+=...you know. If there is a procedure available I would appreciate it.
2. Any heat treat info about W1.4116?
3. This knife is my latest one and I would appreciate any comments. It is ATS34 8,5 cm blade, with damasteel bolsters, mamoth vory handle, ss thong and bronze pins, with black spacers.

4. If anybody is interested about viewing my knives or learn more about me, I finally made (after lots of time) a new site. Any comments would be welcome.

If there is a procedure available. 1. AWNSER, WELL I Think that the awnser to this one is the one you don't want to hear! Pratice:p Pratice:p Pratice:p !On a less sarcastic note I will say keep trying till you find what works for you. if you are getting a lot of chatter on the flat grind platen while grinding it might be out of true? Put a level on it or a ruler and see if it's still flat? If its not you will never get the grind lines straight! you can flatten it out on that 4x36 grinder in you shop photo. remember to heat treat the palten once its flat again.
3. This knife is my latest one and I would appreciate any comments. It is ATS34 8,5 cm blade, with damasteel bolsters, mamoth vory handle, ss thong and bronze pins, with black spacers. 3 AWNSER, the picture you have in there is so large I have to look at it in pieces and its blured. good luck! :thumbup:
 
I usually grind the bottom first to get the main grind just how I want it and then add the top 'chute' to match the asthetics. I bet you'll find just as many do it the other way for the same reason! I'm not sure one way is better than the other. It's just what fits your style of grinding.
 
I grind the top edge first. It will, by necessity go lower than the point, that's normal.
Grind to finish grit on the top bevel as you won't want to have to grind on that when it's in it's finished state, so to speak.

Now grind the bottom bevels and bring the grind line up slowly where the tip is that's got the top bevel line lower. You gradually bring the bevel up as you go through the grits till on the finish grit, you make the bevel split the point. In other words, the top and bottom bevels meet at the exact center of the point.
You grind all this stuff by making a pass or two on one side, turning the blade and making the same on the other, always dunking to keep the steel from really overheating. You'll create less stress in the steel and it won't want to warp so much in the heat treating process. That should be done with any blade you grind.

When the blade is heat treated, you won't have any room to be messing around with the grinder in that area without screwing it up.
Either buff it out, scotchbrite it, or handrub it. It's already at finish grit so it shouldn't pose any problem.
 
Thanks for your answers, I think I start getting the point. But when I say grind I meant grinding on the wheel. Can I grind both top and bottom on the wheel? I have never tried flat grinding and looks tough to me. I suppose what Mike Hull says can be done on the wheel. Right?
The picture is too big but I have not the right program to make it smaller without making it too poor. I will try to find the photoshop, people tell me is good.
As far as practising is concerned I try my best. I have a bag full of crap blades.
Thanks again.
