Anyone have any suggestions on the best way to hold hidden tang knives while grinding them? I am working on my first one and its kinda like a pig...no way to hold on to the @%#%%# thing.

Just slip a set of vise grips on the bottom side of the tang(in conjuntion to the side that you are grindeing)up close to the choil area,being careful not to scratch the choil area.this gives you a good handle to hold onto while grinding.......Hope this helps,Bruce

try this
drill two holes in the tang
and tap them and screw two long bolts
into it that gives you a good firm grip
and you can control the pressure
on the tang,works great put a nut
and lock washer to stop the bolt from going all the way through to the other side
hope this has been of some help.
 
The best thing I have come up with is just a simple little fixture.

I took a piece of 1.5" round aluminum stock that was about 4.5" long. I ground two flat sides on it (parallel to each other). I drilled a hole in one end of it large enough for a tang to fit into it. Then I drilled two holes into the flats on that same end of the rod and tapped them (so screws can be ran into the rod perpendicular to the tang to hold it tight).

The holes are on the centerline of the rod, in line with each other, and about 1.5" apart.

I just slip the tang into the jig, tighten the allen screws down that I put into the tapped holes, and grind away.

This is super easy to make, and gives a uniform shape to hold onto when grinding either side of the blade. I ground a few little grooves into it to improve grip.

Hello,

Heck ,just hold them in your hand ya have to be able to feel the steel and holding onto a pair of vice grips doesnt cut it(no pun intended) If the blades to hot,just dip it more often. Trust me its the best way to learn,just hold it.

Thanks for all the advice. Dont know which one to try first. Does anyone have a favorite rod for welding the all thread to the tang on ats-34?
Thanks again

DO NOT use allthread, welding all thread to a tang is just asking for trouble. The stress risers created in the allthread will cause it to break sooner or later. It is better to use a grade 5 bolt of the correct size cut off the head and bevel the smooth stub for your weldment. Better still would be to thread the tang that you have. I have never welded ATS-34 but if welding a carbon steel bolt to stainless use 309. If you are using a stainless bolt and have acess to TIG you can cut a thin strip of the knife steel and use that as filler rod. If you weld the bolt to the tang it will requre an anneal otherwise the weld area will be brittle. Another solution is silver BRAZE. Brazeing will not bring the parent metal to a high heat as will welding and you may be able to skip the anneal cycle. Test this on some scrap first and give your joint a bend test, you wqill see what I'm talking about.

Why am I good enough to fix my mistakes, but not good enough to keep from making them in the first place?
 
ATS34 won't weld without some noble gasses involved. As for holding onto the blade, I usually just build up a handle with duct tape, with some scrap inside it to give it support. Comes right off after with no damage.

howdy,

Easiest way to do Grade 8 all thread is to
braze it in, i use Mule team borax and put my all thread in the slot i cut into the tang then heat up the area hit with Borax which melts into a flux and use Brass Pin Rod and Braze away,, sticks to ats34 easilly if ya do it right.

Hello LRICE

I had the same problem.
My solution:
1. Cut out the blade
2. Grind the blade
3. cut out the tang

It's much more easier to grind (and to hold the angle), if you have the full piece of steel in your hand.

Allen, is you braze job then unaffected by heat treat?
