Introduction: Build a Disc Brake Utility Hatchet

About: I enjoy building things and being creative.

This build came about as I was going through my shop and looking at some random parts. I figure the bike brake is pretty good steel and will hold a nice edge. I found some other parts and leather to really make this a nice project. Enjoy

I also made a carving knife set with other parts of the disc brake, check it out here!

Step 1: Round Up Your Parts and Tools

For this build I can't give an exact parts list, I kinda threw together some odds and ends I had laying around. But I will give a quick run down. I put the back spike and cap to add weight. The thin metal from the brake is pretty light. Parts: used bike disc brake, wood for the handle (I used diamond willow), 1/2 or bigger steel round rod, steel cap, leather, paint & primer. Tools; band saw, grinder, belt sander, leather working tools

Step 2: Cut and Fit

Get your parts together and figure out exactly how you want it to look and function. Trace out the blade. Using a grinder or band saw cut out the blade and shape other materials. * be sure to have water handy to quench the hot steel. Do not over heat* use your safety gear!

Step 3: Prep and Paint

Sand the metal parts, prime and paint

Step 4: Leather

Gather some leather strips and stamp a design into it, this will form the handle. I also cut some black strips for the top and bottom of the handle. I also cut some super thin strips to tie down the blade and spike.

Step 5: Finish Up

This would be a good time to gather all of your parts. Sharpen the blade. Install the blade, spike and cap with the thin leather strip. You may need to use epoxy to hold things in place, but I did not. Do any wood finish you want here as well.

Step 6: Bonus: Sheath

I built a quick and simple leather sheath with snaps and rivets. I won't go over the details but I think the picture explains it well.

Step 7: Final Thoughts

It's sharp! I chopped some small branches and wood and it held up perfectly. The steel hold a good edge. My only major concern is the top hole in the blade creating a dent or wearing away. Thanks for looking!

    Cool project! It's always fun to see repurposed items.

    This tomahawk done with brake disc, to be cast iron, porous, can not resist the shock. This alternative made with motorcycle crown is more efficient. It is a very hard iron!

    why not use the rests of another disk brake to weld together a handle.

    That thing is awesome. I live in the middle of nowhere so there a hundreds of dead vehicles and bikes so finding the parts for this won't be too hard. In fact, I might just go look for what I need now.

    As a side note, all I'm thinking of is making a whole bunch of throwing axes...

    Looks amazing. As a person who likes biking and is in need of a hatchet, this might just be my next project.

    I'm going to do this, I'm Gonna get a disk brake and an old broom handle. Then saw a line in the bro handle, secure the disc brake axe head. THEN BOOM

    Awesome 'ible. I made one out of a circular saw blade instead of a disc brake, works great. Thanks

    Woah. Gotta make this! Awesome!

    Very cool, I like giving new life and purpose to old parts. I made a hatchet from a window regulator gear.

    Thanks, I love repurposing old parts into something useful. Feel free to post a picture of that hatchet you made in the comments, I'd love to see it!

    Looks great, however that looks more like a battle ax than a hatchet!

    That thing looks pretty gnarly man! Good job.

    I made a hatchet similar to this one, but instead of a disc brake, I forged the head. Unfortunately I was too zealous in my youthful pounding and made the head a little too thin, so I can't actually use it for anything really helpful - it's maybe limited to home defense. :P
    I did make an easy, effective case for it though, which I have been planning to make an I'ble for.....

    большей ерунды в жизни не видел...

    This is a cool idea - I had a free afternoon and my bent brake disc and so, why not? All made with an angle grinder (steel cutting wheel, sanding wheel) and hand drill. Easy! Thanks for the inspiration :)

    what was your disk brake from? it looks far too big to be from a regular bicycle

    it might be a motor bike brake
