This is my first attempt at building a knife completely from scratch with only the meager tools at my disposal. So, any advise on the design or process is most welcome and much appreciated.



Quite a while back I had drawn out this design, but had to put it on the back burner to accommodate some of life's challenges. Then, in complete secrecy,
dear wife-o-mine gave me a birthday present of a 4'x 36" sheet of precision ground O-2 carbon steel ($108.00). And so it begins.....

I began by cutting out the basic shape using a mini-angle grinder(not pictured as dear wife-o-mine had the camera).

Once the basic shaping was done, I had to clean it up quite a bit using, first, my bench-top grinder for the flat and convex surfaces.

I then cleaned up the concave surfaces using three sizes of grinding wheels mounted on my drill press.... larger curves were done with the larger wheel....

Smaller/tighter curves were done with smaller wheels....

With the blade fully shaped and the edges clean and smooth I could them get a better "feel" of what adjustments were needed for pin placement and handle shape.

Next, I drilled out a few of the holes, and began filing out the lanyard notch on the butt of the handle. I need to get a 1/2" HSS drill bit to drill out the largest of the four holes in the blade.

All holes(except one) and lanyard notch are now roughly shaped and drilled out.

The next step is to finalize the grind lines for the blade edge then begin to grind then in using my bench grinder. That's the next chapter in the saga.
 
After grinding in the upper bevels, I realized that my handy-dandy Super Jig would not accommodate this big of a blade for grinding the main bevels. So I had a brainstorming session and came up with a rather simple modification. I purchased one of those magnetized kitchen knife strip thingies, cut off parts of the thin aluminum casing, and screwed it onto the jig. The newly modified jig now holds the blade securely and will do the job quite nicely..... I hope. Now if only my 14 month old daughter Miss Avery, Queen of the Known Universe, will grant me time this evening to disappear into my dungeon and get to the bevel grinding.

interesting jig for doing bevels. may want to learn how to do it freehand after a while. may not be quite as precise, but i think most of the more learned guys do it that way. imho
 
That's a pretty impressive looking jig that certainly promises greater consistency than my wiggly free hand. Is it seriously screwed to a nice piece of curly maple?!

Wordsmith - Yeah, that's actually a stunning piece with great figure and chatoyance, but it was the flattest, truest piece of wood I had laying around so....

OO442 - I'd love to get to the point where I can do this freehand with confidence. I've practiced on a couple blades, but with varying degrees of success/failure. I'm saving up to get a "real" grinder with longer belts that will make this process a bit more efficient, and allow for greater versatility.

I saw a picture of that jig design elsewhere and had a go of it with what I had in the shop. It works, but I think I can do a lot better with more suitable materials.

Thanks for the comments folks.
