Seems spine and handle are flat I glued this piece of micarta to jig so I don t need to adjust blade position every time I switch sides .I grinded several bevels in different angle and then all that grinded on slacked belt .........with my jig of course .
Forgot to take a picture of all those bevels. they looked so cool :)

And here it is ....................it is 0.10mm on edge , I will sharpen it in normal way on 20 degree and then flush everything with hand on soft backed sand paper ...I like how stiff is blade , if it was full flat it would flex lot

I tapered one side of handle and I after that drilled holes for pins .I almost forgot to do it before I taper other side 😂 What I will change are pins , I will use one 3mm then 6mm and last one 9mm .I also drilled that two holes to remove some weight from tang . I have scale from walnut only 10 mm thick , that is not enough to make that *guard * ? It is to late now so I will taper tomorrow other side, thickness would be 1.5mm .

I forgot to mention . . .. .. . When I grind bevels with jig on grinder I never pass over with tip of blade center line of belt for several reasons, but irrelevant here .So when I switch to grind on *slack belt* ..when tip of blade came in the middle of belt ......................tip of blade was GONE 😂 the tip disappeared / about three millimeters / in a millionth of a second !! I understood why, but it was already too late :( I reshaped the tip of the blade and done job ...... live and learn :(
Ready for handles and for convexing edge .I tapered other side and since now both sides are equal, I surface ground in one pass the other finished side with 40 grit belt so epoxy can hold better .

Finish on bevels is from 40 grit ceramic ...one of advantages of using a jig :p

I like how it cut ......blade thanks to angled cutting edge *stay* in that area . it does not go forward towards the belly while cutting ...

Knife was HT on 830 Celsius and quenched in brine .... when I take it out of brine I have the feeling that it will explode in my hands at any moment :)it was tempered on 180 Celsius and I think it is to hard as it is now for this knife .So I will wrap something on tang and I will use it couple of days to see how will behave. most likely I will temper it on 200 Celsius ............
And now I see that I forgot something ...................to grind that false edge /whatever you call it / on the spine :mad:

Well done man! You may be the first one with a finished knife if you keep up this pace.
 
Looking good is that bevel mostly hammer or did you finish with the forging at the pics you posted a few days ago?

You may have finally convinced me to get one of those plunge line guides. That's a pretty sexy looking piece of steel.

First time using it..... I hope to get Better.
(I'm a free-hander)
Idk if it would work good for those angle jig guys?

I Really do like it though.
It's a little heavy, but it's well balanced.
I looked around a bunch. I wanted carbide, stainless, and wide enough for kitchen knives
 
I've been lurking this threadfor a while now and love the idea, can't wait for the bowie quarter!
I decided this knife will be my KITH knife as well and it's a good opportunity to document it here.

This design is an all time classic, however I wanted to do something more personal instead of following it 100%. The most major difference is going to be the construction, I do not enjoy making full tang knives at all, therefore I switched it to a hidden tang. Also, I have yet to decide whether there will be a guard or not.

The steel of choice is 1084 and did stock removal to make it within a reasonable time frame. Profiled and rough ground and ready for the heat treatment.
I didn't have enough time to do it today, that's why I moved straight to the handle.

The ricasso is 4.1mm thick and the tang tapers to 3.2mm. Marked the center and drilled some 3mm holes. The backside is drilled with a 6mm drill bit 80% of the way. This created a recess which makes the fit easier and later on will be filled with epoxy and create a moisture barrier.

Since micarta cannot be peened like a metal guard to close up any tiny gaps, I used my file guide while filling. This ensures I will not overdo it while filling.
This step is a bit repetitive, file a bit, try it, replace the file guide, file a hair more and retry etc.

With the guard fit, the handle is next. A block of walnut will work lovely in this case.
Marked the tang and went straight to the drill press.

Proper alignment is crusial. I drill my the tang slot a bit deeper than the tang, later on I will have to grind the top a bit to make it fit perfectly to the guard.

A ghetto made broach makes quick work of the final fit up.

And here is today's result. Tomorrow I'm going to heat treat it and keep going.

Really cool thread, keep the pics coming.

N Natlek let me know if you want, and I can put you a block of walnut in the post free of charge.
