elliptical grind

By elliptical grind I assume you mean a somewhat elliptical cross section to the blade with out spine being sharpened to a second edge? I like this form, and wondered if I was the only one that ever noticed. This seems to be a natural evolution in form for me from hand filing blades. I've also "swamp" the spine on almost all the knives I make, that is make spine a shallow concave curve, and also on the sides,i.e. thin an area below the spine and let it feather off to guard and tip area. Like I say, this purely personal evolution from hand filing. Now a perfectly geometrically perfect flat grind seems clunky and "wedgey" to me. Are we thinking along the same lines?
 
Fox Creek, can you post a picture of one of your blades to show this style of grind? I would like to see it. If you need help posting a pic, let me know, I'll be glad to help!Take care! Michael

Aren't we talking about a convex grind.I try to make a constant curve from spine to edge.Sometimes with a little drop about 1\2 inch from the edge.
Take care

Try to imagine a fish shape. I attended workshop with Karl Schroen teaching forging. This is the grind he is using on many of his knives. Spine is not sharpened. Makes a very strong knife that goes thru material very well. I also wonder why it isnt used more often. Somewhat elegant strong look to it.


 
Here is how I do it: I made an attachment for my wilton that holds two rollers on 5 inch centers, no platen. it's a 5 inch slack belt. Using the tention control I can control the shape of the convex. I grind free hand, edge up! Tention on the heavy side works best for me. Hope this helps!

L6, I don't have a good example on hand at the moment. Iv'e got three small knives in the finishing stages, but they aren't the same thing. I'd love to post some pix but do not have access to a scanner or a digital camera. Gee, I don't even know if it would come across in a photo. I'll see what I can come up with in the future. thanks for the expression of interest!
