Well I was happy with the hollow grind, so lets try something fun, a tapered tang!
My first one and I realy enjoyed doing it!
I kept just a bit over 1/3 of the original thickness. I think it screams out for a handle with liners to show off.

Very Nice!
 
So far I have used / bought / steel from Germany. Nothing special 52100, 80crv2, 1095 .... they were all good, the thickness the same everywhere, without any dents or bumps .
CPM steel , I can t say that I like it ! Uneven thickness, unevenness, depressions in the middle of the steel across the entire width ????
This was 4.5 mm and I must to take down to 4.31mm to get even surface !! Are all CPM like that ? This is CPM S30V............I mean blank on picture

Weird ...... same weight both :mad:

CPM steels are sold over thickness most places and need to be ground to final thickness. If I order .125” CPM steel it comes .145-.15” thick Alpha I believe precision grinds all Crucible steels they sell.
 
I don't really understand what you're asking ? I clamp blade to jig , set angle on work rest and grind that hollow bevel ?
So you do :) i mean that the hollow doesnt follow the curve of the blade. Basically you just grind less on the tip to have same thickness on the edge?

That make sense .This is what I am talking about , all these rectangles are lower points.I almost destroyed guard for that knife because of difference of thickness ....

I don't know how to explain that in Macedonian Fredy , let alone in English 🤣 On the contrary , i grind more on the tip ,blade is some kind of distal taper .Soon i will grind that blank and i will take pictures in at different stages and it would be clear how I do that ....

I'd be very interested in seeing how you hollow grind with a jig!

I am running it through my head and am still confused how do you achieve consistent edge thickness. I guess it's one of these thing where you have to be on the grinder and have the moment of relevation 😂

Take a look at this drawing and think a little what is going on . . . . where the belly begins the angle of the blade towards the belt changes
If we grind the part of blade that is 40 mm wide to one millimeter thick on the edge and keep grinding parallel to that edge thickness , edge thickness will start to increase where belly start . Where belly start edge would be thicker and tip even more thicker , just to get idea what I am talking about , if anything make sense ?
If I explained this well, you would know what to do if you want distal taper . If you want grinding line to follow the curve of the blade you need to start to pull tang towards you when you get with grinding where belly start

If you grind full flat grind on 40mm wide blade , what kind of bevel you will get if blade is 30mm wide if you grind on same angle on work rest and what kind of bevel you will get on same angle on work rest if blade is 10mm wide ?

Natlek, wouldn't the angle of the bevel start to get blunter and blunter as the tip starts to go " under " the wheel more as it gets narrower?1651967639766.jpg
