This kitchen knife was an experiment, approached as such, that taught me some really useful stuff. I'd like to share for the benefit of other novices.

Specs:
1/16" 1095
OAL 10"
blade: 5.5"
handle: unknown wood (see other thread, maybe someone will know)
3/16" brass pins
tru-oil and Flitz gun wax finish

I knew 1/16" was thin, but the material was cheap and doing a big knife starting thin instead of grinding tons of expensive material away seemed like a good idea. I approached it all without a great deal of emotional investment or plans to make something utterly beautiful. The idea was to play around and learn something. I did:

Lessons
#1: My skills do not yet extend to symmetrically grinding 1/16". The angles are just too shallow.
#2: chisel grinding 1/16" is perfectly reasonable
#3: hollow grinding 1/16" is particularly stupid (for me)
#4: long, wide blades are harder to keep flat against the belt, causing all kinds of horrible divoting. Then there's not much metal left to sand things flat when you're done. Match grinds to thickness to skill.
#5: for long thin material like this with an obvious weak point, through-harden to produce stiffness at the neck. This knife was pushing the limits of the 2-brick forge.
#6: the angle btw the edge and handle is critical to getting the entire blade onto the block for a kitchen knife. I knew this going in, and it was borne out in practice. As is it works pretty well, especially if you work towards the edge of the counter. But it's right on the boundary of being not quite right. Allocate more angle or blade height in the future.

Happy Lessons:
#1: this unknown wood makes a decent handle
#2: use 3/32 next time and don't be afraid to go for it. It's totally achievable
#3: even an ugly-ground barely finished homemade kitchen knife can out-finish, out-handle, and out-perform my old decommissioned crappy Chicago Cutlery! Woo! This one is going in the block with the Henckels. Get that useless Chicago chef's knife outta here!

Good for you. I'm sure if the heat treat is anywhere in the general neighborhood, it will outperform many off-the-shelf knives.

Now take what you have learned and make another one. They only get better.

thats pretty nice. take a pic of the wood close up and send it to mark at burl source, and see if he can guess what he is. he knows a little bit about wood.
 
Nice looking knife!

One thing I like to do is to make a cardboard, plywood, or plastic profiles to get a rough how the ergonomics are. Then I use it as a template.

If you don't have any sentimental for the Chicago chef's knife, you could do a regrind on the blade to improve the cutting geometry. I reground and rehandled an Ontario work knife(1095) for kitchen use. It came out nicely and gets used daily.

Real nice.I have some 3/32 1095 coming,i may try something similar.Could that be palm wood?
 
Get yourself a 6x48 sander with a cast iron deck. 1/16'' is easy to rough grind on a 2x72, but needs to be finished on a flat sander. I make 18th c. folder penny knives with 3/64" blades easily.
 
Indeed, I think a flat grinder is the key.
What you can't see in the pictures is that the grind is only at most an inch high on either side. That's how much trouble I had with it! *lol*

Sounds like Mahogany wins the vote. The rest of this stuff is the reddish color I expect from mahogany.

I have two gripes with the old chicago knife:
1) the ergo's suck. I could easily improve the handle shape in about 15 minutes
2) it won't take or hold an edge. I might turn it into a mini cleaver, but that's it.

It paid for itself years ago and warrants little effort to save it at this point.

A small hint about grinding thin blades.Use a paint stir stick cut to the contour of the knife as a backup.It will keep the blades from flexing as much during grinding and make your grinds better with less clean up.

Very cool thread with some good info for anyone thinking of working with some thin stock to grind a kitchen knife. All lessons you learned aside, I think it turned out really nice and will make a great addition to the knife block!

One thing I must mention though. Chicago Cutlery Chef's Knives may not be so hot.........but my good 'ol carbon steel Chicago Cutlery carving blades are some of my most beloved kitchen knives and see active duty constantly! If I'm carving meat, I go straight for the Chicago Cutlery, I love 'em.;)
 
Awe you hurt Jonny's feelings! :D

sounds like you learned a lot from this one. I find that I learn more from personal experience than from reading. Use the knife well, I have a similar knife that I choose to use over Mfg'd knives just because!!! My guess on the wood is Walnut...
 
Don't tease, it's not nice:D

but my good 'ol carbon steel Chicago Cutlery carving blades

I wish they were carbon.... mine never rust. Or cut! Actually the boning knife has been alright, but it doesn't get a lot of use. The chef's knife is just sad, alas. I loved it when it was new.
