Why Does this Happen When I Sharpen Broadheads??

[DEATHMASTER]

To see how much presure you are using take a bathroom scale.
Color your edge of blade  black with a marker.
Place your sharpening device on the scale.
rotate blade with each stroke
Start with 6 to 7 lbs pressure 6-10 strokes.
Look to see the edge is down the center of the blade and you have a burr the full lenght.
Go to 4-5 lbs pressure 4-5 strokes
Next 2-3 lbs pressure 2 strokes
Last 0-1 lbs pressure 1 stroke

I see you all frequently mentioning a burr on the edge.  Instead of using a BIG file flat on a table, I use a 6 inch file in my right hand and I will hit each set 5 or 6 times and then rotate to the next pair and repeat.  I will do this until I get down to 1 and then I'll go at each one with progressively lighter and lighter file strokes until it feels pretty sharp and each side has had the same number of file strokes.  When I feel the edges after doing all this I have never felt a burr.  I take my fingernail and try to feel a part of the edge that is rolled over and I have never felt one.  Every one of my edges is absent any kind of burr.  That's when I go to the other tools to try and get it sharper.  The best results so far seem to be to lightly use a butchers steel after all the file work.  They easily cut rubber bands but won't readily shave hair.

To answer a few earlier questions, on the stone I use 3 in 1 oil before putting the head on it.  When I try the FINE Lansky stone I also put oil on it before using it.  With the 1000 and 2000 grit sandpaper I lay it on a hard surface and push the head forward a few times on each side.  This hasn't seemed to work very well though.

Thanks everyone for the suggestions.

I've read to do 10 strokes on each edge. Heavy with the first 10. Then 9 strokes with a little lighter stroke. Then 8...

I find it hard to do the lighter and lighter thing so I just hold the arrow shaft farther back with each set. By about an inch.

I then follow with diamond sharpener and cardboard. I get some hairs to pop but not "shaving".

Check out this thread. I tried it. It's simple, quick, portable and works on any broadhead but especially well on 2 blades. I've been able to get them sharp enuf before but nothing like this.

Buy a couple of sharpening blocks from 3 rivers. They work very very well for me and use no pressure other than the weight of the shaft. you will be able to shave with them.
