Hoping maybe someone can help me with a handle profile for this knife. It's the first one I'm doing with brass bolsters. Blade thickness is 3/36" and handle material is 3/8" material

 
I don't see any problem with the shape. My only comment would be to use only two centerline scale pins. With the dovetail bolsters, that is plenty of strength.

Thanks Stacy. It's already HT'd so I may not attempt any new holes as I also have a lot of larger holes drilled to remove weight, I may not be able to achieve that anyway, but I will take a look when I back in front of it to see if it is feasible.

I have no other shaping done to it. basically all sharp edges. Are you just saying radius the edges and go with it?
 
Sorry I didn't see that in your OP. How long is it overall? I'm going to 3d model what I would consider doing with it. I have the geometry I just need the scale.

Thanks for taking the time John. 9.64" OA length. I can save you a little time if you want a .dmg or .dxf. If that would help. My original drawing is 1:1 My OP image was just a print job to pdf printer from autocad 2014, I didn't scale the print job I just fit it to screen. Then I exported the jpg from adobe acrobat.
 
Changing the pin location may be a tall order considering all of the holes I have drilled for weight removal. I may get lucky actually measuring it out. But this is what I'm dealing with moving them at this point.


 
I may be using the wrong word, but the 2 on the outside. Contouring, shaping....... That is what i'm needing help with. Something like this. I think it needs more than just rounding the edges. Maybe....


This is just a crop of an image from a google search.
 
It's tough to blend and sculpt the way we do on the grinder with parametric models but here's my best at a quicky. With a little blending where I've left sharp corners, I think the general idea comes across. At the narrowest points, which would be the tips of the bolsters and the bottom of the hollows, they're .188 thick, so half their current thickness. First pictures are where you're starting from.

I can take more screenshots if you'd like.
 
Hey great minds and all that. Meld your sketch with my model and you have what I had in my head.

I like the simple image you posted too, you're just way too thick to simply round it I think.

John, thank you very much that is awesome, and is pretty much exactly what I was envisioning, I'm just not really good at drawing curves. The sketch I posted was just something from a google search. I like that you left off the dove tails as I may not attempt them. This will be my most difficult build so far by a long shot and I don't want to go too far over my head on this and ruin it and some pricey materials. As it is, I'll have right at $50 in handle materials and I'd hate to ruin them. you couldn't by chance post full 1:1 scaled shot of the top and bottom? I would like to try to use them to lay out the curves so I have some sort of guide lines to go by.

Yeah I was thinking the same thing on the other image I posted, that I am too thick for something like that. I went with thicker because I was hoping to do something like you posted with more contour to it. The swell in the center I think would make a very comfortable knife to handle.

Are you using solid works to draw those?
 
We use Autodesk Inventor. We have a couple seats of SW but because I learned in Inventor and don't really do it often I haven't tried to learn SW. I wish I could spend more time doing it and learn a bit more. I know sculpting is possible in Inventor it's just not as intuitive to learn as parametric was.
 
As for scale I'm not sure I can. I could definitely scale the outline profiles and put them in a PDF.
 
I think I got it. I was able to import your image to my cad and use it for a rough guide to mark up my drawing. I can print these off and use it for my guide lines. Think I'm going to drop the dovetails I think I actually like it better without them.

Thanks for the help John.

 
With the brass, you will be less exaggerated in the sculpting. This is a comfortable shape for this style knife:
