This week my dad will celebrate his 46th birthday, so I decided to make him a gift that's useful. Some time ago he used to go hunting regularly so he has one really good Italian handmade knife, but i hope that he will like this one too.

Also this guy: Garra23 asked if i could make an instructable about acid etching so i made it :)

Tools and materials:

  • Angle grinder
  • Sandpaper
  • Files
  • Glue
  • Fe Cl2
  • Used plastic bottle

For the handle I used deer antler and cow horn but that's optional

Step 1: Blade

First I took a piece of steel and cut out the blade and grinded it. I choose this form of the blade because it's the usual form that's used for hunting knives.

Step 2: Preparing for Etching

First thing to do is to put duct tape on both sides of the blade.

Then I drew the lines that I wanted to be etched on the blade and cut them out and also i put some nail polish on the places where duct tape didn't cover the blade.

After that took a plastic bottle and cut it in half, poured water and FeCl2 mixture in there and put the blade in there.

Step 3: Etched Blade

I left it in FeCl2 for couple hours, however I regularly checked, because I didn't want to overdo it.

Unfortunately it didn't turn out the way I wanted it to be, because I didn't sand it enough.


Step 4: The Knife

At first I thought i ruined the blade but when I made the handle and polished it, it turned out quite well, it has that old, vintage look to it. It sits in hand really good, and it's razor sharp, I even was able to shave hair off my leg :D


Hello,<br><br>I have a question for you about acid etching metals. Do you think it's possible to 'dye' the metal a specific color using a similar method to acid etching or not? and if so how would you do it?
<p>Hi!</p><p>Yes! It is possible, however consider that this process makes the metal become weaker against rust! I have tried something similar, only with <a href="https://en.wikipedia.org/wiki/Electroetching">electric etching</a>, but you can simply put the metal into the FeCl solution, and &quot;dye&quot; the metal from light to dark grey color!</p>
<p>very cool knife! would it be much harder to make a sword? by the way, you should be a model, you are georgous! </p>
<p>Yeah sword is really one level too high for me, considering how much work I put in my knives, so I'm sure sword would be quite harder to make! Thanks!</p>
That's a great knife, one question: why, if you had enough steel, did you make the tang so small if you had enough to make it stronger?
<p>Thanks. I did so, because the the cow horn had limited space in it, in lenght, the hole in it was too short even when i drilled it, and I didn't want to overdo the drilling, so i just made the tang shorter! :)</p>
Really Awesome!! You did great!
Haha you even added me in there. Priceless lol.
<p>Glad you liked it! :)</p>
this is a wonderfull knife, did you have to temper the edge and if so did it effect the etch in any way?<br>
<p>thanks! i didn't temper or heat treat it because i took steel from a massive saw that most likely was already tempered, and i think that tempering shouldn't affect the etch</p>
<p>could you do an instructable on how to make a knife without power tools because i dont have access to any :p</p>
<p>wow, if this is quite time consuming, then working without power tools is incredibly hard, i could do it, but i have many other projects, so sorry, most likely i won't do it</p>
how do you make handle?
<p>I didn't make it, it's cow horn, i only polished it, and glued the blade into it</p>
how do you polish the horn or bone?
<p>i used very fine sandpaper (1000 grit and more), and polishing wax</p>
think I found my next project from you good sir :)
<p>awsome, then share it too, when you'll make it :)</p>
how do you make handle?
Haha, shave hair off your leg.
<p>Beautiful work! (And I love that handle, too. :) )</p>
how did you wedge it into the handle?
<p>I glued it, using epoxy</p>
<p>where do you get FeCl2 or do you make. Ps this is aweesom</p>
<p>I got mine at Radio Shack.</p>
<p>its called ferric chloride, i found it on the internet, and bought it in an electronic shop, its also used for etchign some kind of electric circuits. its a salt-like brown substance, and you only have to add water to it</p>
This is really cool!
