False Edge ?

[SKIVIE]

Well, I just received an order asking for a false edge. Its a tactical knife (one of my first).

Im excited to do this since ive been wanting to offer a tactical knife. This would be my first attempt at a false edge.

Questions I have:

Do you grind it first before the other bevels ? Or after ?
Do you grind edge down ? Edge up ? tip down ?
I figured I could just attack it and see what happens but thought some good advice from my friends might save me some missery.

Any help would be much appreciated.

Shane, I generally grind my false edges after the main bevels, and I grind it just like like I do the main ortio of the blad, edge up. So for the false edge, it's blade edge down. Sometimes I'll do both sides of the blade, and sometimes I'll just do one, depends on the knife.

Shane,

I agree with Trenton. Establish your main grinds first. Are you planning to forge/grind a distal taper?

At any rate, grind the false edge with the spine up.

There are a few ways to do it. Seems everyone grinds the main bevels first, then does the false edge. One of the concerns for some is that you have to hold onto a semi-formed blade edge (which is facing down) when you are grinding the false edge (facing up). One way around this problem is to grind the false edge using the contact wheel on the grinder with the blade held vertically. Eyeball the blade from the side as you grind.

Another point is that because the false edge has such a small surface area, it can be challenging to grind through the grits as it doesn't "follow" the surface very well when using a platen or hollowgrinding wheel. However, because the surface area is so small, its quite simple and doesn't take long to just grind it out with 80 or 100grit and then sand it out by hand.

Cheers. Jason.

I use exactly the same technique as the main bevels pre-HT. After the HT, I do less finish grinding on the false edge as it is already to finish proportions. The mains get a bit of stock removal and, of course, an edge.

Enjoy!

Hmmmm, Lots to think about. Thank You.

I did a practice run last night on a ruined blade and it came out fairly nice to my suprise.

I had my Small wheel attatchment in My KMG so I ground it tip down using the SWA. It made a nice radius half way up the spine on the blade where the false edge stared and smooted out well at the tip. I then took to hand sanding. When I was done I was wishing it was the actual blade, now I'll probably mess the real one up.

Thanks again for your help.
