My First Completed Knife


Recommended Posts

well your light years ahead of my first one, Great job! That textured copper was just the thing to add some " Umph" I like it!

Great fit and finish, far better than my first! Two things I see to think about for the next one, though: lose the step-down from handle to blade spine. That should be an unbroken line for good visual flow. 2. The handle still looks a bit blocky somehow. These are both minor aesthetic points, but I think you'll find your next knife will look even better if you incorporate them. Great job!

Thanks again guys. Alan, I agree with what you said, and definitely will work on those aspects on my next knife. I plan on doing a full tang for my next knife, so the handle-blade transition should be smoother.

Great job! I wish my first knife turned out that good. Unfortunately though, I quenched it today and I think it cracked. :(

Nice job Eric.

So don't put a handle on it......that way it isn't your "first knife" :P

It's just your "first blade."

I like your thinking Josh!

I'm a fan of copper, so I'm definitely digging that. Maybe if the handle was narrower? It kind of feels like whatever you would call a Japanese paring knife.

Do you mind if I ask how you handled the heat treating? I've got a bearing race sitting in a drawer that may have just found its new purpose.

great job on the copper addition....to prevent galvanic corrosion make sure both the knife and copper are insulated from each other with heavy coats of epoxy or many layers of clear nail polish at the point of contact between the copper surface and the blade connection...

I never knew this was a thing, can you elaborate please?

If I understand it properly, the greater the difference in electrical potential between two materials, the more likely they are to experience a galvanic reaction. The end result is one of the materials gets eaten away in the presence of an electrolyte, like sweat.

Cheers, thanks for sharing, never knew such a thing would happen.

in the case of copper and steel in contact with each other it would typically take about 2-3 years for the decay process to completely ruin the blade...first noticeable signs of decay would be a a white chalky looking powder forming on the knife close to where the steel and copper meet

Galvanic corrosion only takes place in the presence of moisture, so if you keep everything dry and oiled you have nothing to worry about.  Now then, if you bury that sucker in wet acidic soil you'll get serious corrosion in a short time.  For most of what we do this will not be a problem, as you can tell by all the blades with copper/brass/bronze on them that have survived for centuries.
