Yes. I like the new design but didn’t know how to resolve the interference with sharpening. That is a good idea.
On another ‘point’, I just tried your fake knife on a fake bear and he stopped in his tracks.
Now, all you have to do is spit in his mouth. 
Since we were doing all this knife talk, I remembered that I had a cherished Buck knife and wondered how it stacks up with wants and desires of my idea of a favorite knife now.
To start with, I remember it being much larger (more than 55 years ago):
But the one thing I noticed is they make it easier to sharpen (and it appears they do just what Henry suggested) by delaying where the sharpened part of the blade starts.
I think you baited me with the ruler. here a 3d model.
I am printing one now.
Rapid knife prototyping workflow.
You grow to fit the aquarium.
Where I grew up, I got to know [Ray Appleton](Ray Appleton Knives | Arizona Custom Knives - Arizona Custom Knives https://iqknives.com/products/ray-appleton/). 6’6" tall lanky guy, no use of his right arm (Vietnam injury).
Lived in a run down house, small 1 car detached garage/shed with his EDM, Mill, and Lathe, and a few other things I did not know what they were.
Worked at the local grocery store and he would bring in his current knife he was working on and let me see them. Helped me with a couple projects of my own as well.
I wanted to throw this link in. His pushbutton locks were stunning. 1980’s work.
No such thing. I just included it because if it were me, I would like the handle about an 1.25 inches longer and probably 50% thicker. You are so fast with modeling!!!
@Sticks…very cool!
@TinWhisperer - model the knife to YOUR hand. What feels comfortable and allows the proper ergonomics and leverage for YOU. Then go for style. Function first.
Printed out great. I printed the handle vertical this time. Only 1.25 hours .
Well since I don t sleep anymore.
I modded the prefect buck knife design.
Then I could not leave it alone.
And tried the OG in this red black colourway. I like it.
A little excessive I have replaceable blades now so I can just print and try new blade types on this handle. I think I’m going to print some vertical handles like this more. I’m contemplating cutting a piece 1/8 inch saw blade and epoxying it in a solid printed handle like this. I wonder how well it would work?
To think, someday soon metal 3D printing at home, print your own knife, just temper and sharpen.
And yet another in all black
I have a plan for that.
I 'll put several set of latex gloves on my right hand then grip a piece of play dough .
Then 3D scan it and import to fusion . This should give me a solid starting point.
Maybe this weekend.
It won’t be any cheaper than buying since all of us, generally, make numerous prototypes before we settle on the final design. But, oh so satisfying to be creative and do exactly as you say: fit, function, finish.
Alright Tin, that has two purposes that come to mind:
Nah. That is what the dog on my avatar is for.
Amazing . Clockwork and Jewelry
Turnips
I think you will get a good idea of how it feels and functions.
I made some splitting wedges for making kindling out of 1/4" steel. Nothing special. (This predates getting a plasma cutter and my new welder.)
Then I sharpened it again and did a very crude tempering stage by heating with a torch and trying to keep it in the blue color range for a few minutes. Then allowed to cool in the warm air of my finishing room. Much better results and holds a decent edge for this purpose. A friend told me that the one I gave him (5 years ago) “works great…uses all the time…and has never needed sharpening.”
So I think it would give you a good clue if you are on the right track.
@TinWhisperer is going to have the world’s largest collection of dull plastic knives by the time he’s done having fun.
Keep at it, plastic is cheap compared to steel and I suspect you are learning a lot about what you like and don’t like.
I really like the way this one looks, but I do believe the half circle cutout will add a weak spot in the knife. Fill that in and it’s a great looking blade that should function well for tons of things.
Trying a medium sized cleaver today . Silver and marble speckle handles. About 7" in total length.
The handle is somewhat too thick towards the back for my hand.
I was inspired by this Gerber Tri-Tip - Green | Gerber
And I have another medium-sized cleaver in the oven. … going to start running out of plastic. 
It adds up! Sounds like you will be ordering more filament! Because I am reasonably sure that your desire to "create"is not going to diminish.
