Hey guys, I am thinking of doing a small hawkbill blade of about 3 in. The problem is I cant figure out how to grind the thing..I've praticed on wood but the ends get ground down faster than the middle.. I am trying to do a flat grind, is this the problem? Is there a better grind for this style?? Thanks :thumbup:
 
I don't know what size grinder your using but when making kerambits with the simmaler size bladeI use a 1x42" the 1" belt makes for good curves. It's just what works for me.
Peace

Grind on the edge of the platen. Keep the steel moving or you will grind grooves in it. Good luck.
 
I just started doing this exact thing (first knife) the other night. All I really learned from the experience is that wood dust trapped in tight corners+ glowing steel dust = fire.

Steelswing,
Can you provide a bit more infomation about your technique? Do you grind on slack belt, flat thing, or wheel? Any jig or just free hand?
Thanks :)

rocketmann,
Since the simple sometimes alludes us, have you considered just using files? I think that until my grinding skills go way up, this may be the way I have to go.
 
i just cut the arch then grind on the edge of the platen
same as any other blade but the edge will not flat spot
when i used my 1x42 i made a half round platen and that worked well too
oo leave a tab to hold on to at the tip that helps also keep the blade moving or like said you ll gouge it out
hope this helps
 
Thanks for the info butcher_block, I'm on my first knife and have discovered that there isn't a whole lot of steel left to figure out how to grind bevels :) No tip left to hold onto so I guess I'll just sweep it off the platen in one direction.
 
i made my curved platten my self with a bit of angle iron and a pipe
a few tack welds later i was back at it
also it helps hog on the round least i like the way i was doing it
had a hard time boging the little delta when all that was grinding was one little spot kind of like grinding on the edge of a standerd platten but with more control
 
AS you grind, keep the center of the blade perpundicular to he center of the belt. Rotate the blade ends up or down to achieve that, the grind will follow the curve of the blade. Works for hawksbills or blades with lots of belly.

I think we were talking about the bevels, but then again maybe not :rolleyes:
 
Oh yeah, I guess not, never mind then...

Well I ground my profile by putting it on the pulleys and just kept moving everything real fast and varying pressure. If you have a lot of time, a dremel might be nice too.
 
Can you grind a hawkbill on a wheel grinder? The school has both a big and small grinder, but no belt grinder.

Of course you can. If you want the hawkbill with a curve the same as the wheel, perfect, otherwise just use the edge of the wheel. BTW, nice school to let you make knives on their machines :cool:
 
my first knife ended up a little like a hawksbill...not on purpose, just when i was grinding (trying not to have the blade sucked into the grinder) i sortof turned what was going to be a wharncliff into a hooked blade...it still turned out fairly well, and mounted on a 2 foot dowel, makes for a good brush cutting tool.

We'll see if they let me. I need to catch up a little on my work first before I ask. I have seen them let people work on knives before though. I don't think there'll be too many problems if I get more of my work done.
