KME flattening near tip..??

[13aphomet]

Hey guys, looking for a little help here. I'm a beginner/intermediate sharpener and have a KME system.

I've noticed when I've tried to put a new angle on knives, that I'm seeing this flattening of the blade profile toward the tip.
My end result is a very very sharp knife - but I really don't like how it's like changing the shape of my blade. It's almost like it's trying to change my belly into a tanto-ish type tip.

I realize this is probably because I'm using flat stones to sharpen a curve, but I'm looking for what I could change about my technique to keep the blade the same shape.

As of right now I'm moving from heel to tip in an up/down scrubbing motion until my stone is about half off the tip, then I move to the heel again. Rinse and repeat thru the grits, getting a burr etc...

I'm just really hating this flat belly thing I've been getting. Help!!
Thanks!!!

hey.

the tips are looking good to me.

i doht understand or see your problem.

maybe you can take a photo of a drawing, showing more clearly ...

If you follow the edge from the heel to the tip, it almost seems like sharpening the knife took the some of the belly off of the curve up to the point.
It is kinda hard to see in the pics, but I feel like the area from the tip to the bottom of the belly is kind of more straight than it should be. Like I lost a little bit of curve up to the point.

Maybe I'm being picky, but it seems the consistent sweep of the blade shape has been altered and I just wonder if anyone else has noticed this... maybe I'm crazy. I really don't think so though.

To much pressure or staying in one spot to long

Doesn't look horrible in pics but I know what you are saying (I've done the same when first using a fixed system)

Lighter pressure and widen your lateral movement in your up/ down motion near the tip

I do seem to overlap my strokes really close together. Like as I cross from heel to tip, I'm probably doing like 30 up/down motions.
I thought maybe it would be smarter to treat the entire belly with a sweeping motion. Do people do that?

I thought this because when ya think about it, a flat stone isn't going to make contact with the whole edge as you're crossing the belly - it will just like teeter on a point.

Thanks for the advice yoko, I appreciate it. I have an s90v para2 coming in with a slightly broken tip - so I guess we'll see what happens.
