Applying a chamfer to an extruded-spline edge

[MechanicalChef]

This is mostly for practice and boredom.

Here is my progress to this point. I have the profile extruded, and the grips cut away in a form that pleases me. However, I'm now trying to get chamfers on the blade itself to duplicate the bevels similar to those on the blade of this knife.

This is my sketch. The sharpened edge is composed off a line and a spline-curve. Once again, what would be an appropriate way to make this work? Thank you.

I knew my issue was geometry constraints being violated, but I finally tweaked enough to get a valid output. I'm assuming the chamfer starts to intersect my notch right beyond the grip and starts freaking out.

You can get the bevelled edge around the serrations by using a ruled surface. I made straight cutouts representing the the serrations, and then used the ruled surface "tapered to vector" option, and cut with the surface.

Nice use of linked photos!

I wouldn't ust chamfer for this. I would make a split line down the median (the blade edge), then sweep a cut to bevel the edge.

I probably would have done what dezignstuff has shown then create a plane at the blade-cutting angle and then cut-extrude.
