Picture of Fish Bone - Knotless Gear Tie

If it’s worth tying it’s worth tying with paracord. Only thing is, untying knots in paracord can take superhero strength. My contribution is this little guy, “Fish Bone”. It’s a no knots cord tightener without serrated edges. You can use it where you would normally tie a knot. This Instructable documents how I designed it from thought to reality to include how it went from low tech graph paper to high tech finite elemental analysis.

I took this instructable to Kickstarter where it was well received. You can check it out here. Thank you everyone for your support. Brent

Step 1: Idea & Proof of Concept

I wanted to design this specifically for paracord. For starters I went to Sketchbook and doodled some ideas. I settled on a rod encircled by a spiral. I wasn’t even sure this was going to work but all I had to loose was a coat hanger.

Once I had my sketch made up from wire I began to figure out how it would work. After looking at it for a while I realized it looked like a fish. From here on my design was geared around a fish bone. 

For anyone who’d like to try, the next couple steps show how the wire fish bone is made.

Step 2: Prototype, basic shape

Start by taking a coat hanger and cutting out the long bottom section. Bend it about 1/3rd of the way down over a the shaft of a screwdriver. Bend the longer end at 90 degrees. With the short end against the shaft, wrap the long end around both. See the pictures. Cut it to length so that 5 coils are left. File any sharp edges.

Your design inspired me to make I own gear tie tool. Since I needed a new pendant, I decided to integrate the two. Here I have my "Bird of Prey" gear tie/tag.

This is awesome. I really like how the tie resembles a cross knot. Good work.

Hey i thought of this idea maby u could show it off and make it for me how about u make ur knotless gear tie out of an old key that way u could reuse the keys and i think it would still work reply back to me what you think of my idea

Interesting Tool ! Well thought out. I have worked in the metalworking sector for most of my adult life, aircraft industry, dairy industry, general sheetmetal work. I have an affinity for stainless steel,Titanium, and ali. I think that 6061-T6 ali would be ideal for your product, a lot easier to work & finish, can be color anodised.
Cheers,
Dennis

So you are the one who came up with this idea that just about every Instructables member knows about? That is really cool.
Mrballeng (author)  Reiff1 year ago
That's me. It all started with the pocket size contest. I would have never though of it if that contest wasn't up. So my advice is participate in the contests even if it's just for the sake of participating. You never know what you might come up with.

You know what I'd really like is a whole Instructables one the different ways to use paracord one the fish bone.

Where can we buy these
Mrballeng (author)  jgarcia871 year ago
Www.fishbonefish.com

This is a great idea!!!
Have these been mass produced because they are prizes in the great outdoors contest?
Mrballeng (author)  shotgunshane1 year ago
Yes. So far we have had more than 20,000 manufactured.

Very interesting, I will do my own. I discovered the usefulness of hooks when I did my rack for car.

Using these "fingers" you can load or unload the trunk in seconds, without threading the hank of rope over and over.

I was so bold to take one of your pictures, run through photoshop and make this pdf out of it.
It yields a 100 mm / 4" long FishBone.
When printing pdf, you can easily scale to get whatever size you would like.
I am making a 133mm, 100mm, 70mm and 50 mm version, just to find out what more purposes this little neat magic thing has.
awesome dude, I don't have many tools but I will do the best I can to cut one. Your pdf will make it a lot easier

Have you thought of selling this to Lee Valley? They would be totally into this. They sell primarily tools and equipment and love quality items like this. They have a magazine too which has a loyal subscriber base.

I like the new Piranha Gear tie You made. Looks pretty cool.

Still loving your design. Here it is integrated into my knife. How's kickstart coming?

congrats, awesome design.
mastergabe1 year ago
this is great i'm defiantly making one but it would be good if you posted a blue print of the basic shape so people could trace it on to the aluminium flat bar.
Yes, you have many great pictures, but please add 1 drawing with 1:1 scale (flat, no perspective) so the DIY among us can make exact replicas of your final design.

Hi, congratulations on your great project.
What do you think about injection molding? This is for mass production (above 500 parts/year), you will have low costs. The downsize of this is that you must pay for the injection molding tool around 10000EUR and your model will strain at 30LBS, but you can put in glass fibers and get to the 45LBS (this is my thought). Make a FEM simulation and you will see.
Have a great day
Oh yes, and the then when you sell it, you will have a lot more profit.

I love it. Any inspiration derived from a product called knot bone? Yours is much more creative and if they were side by side I would go with the fish bone. Great job and congrats.

"THE SNAPPER" is made of aluminum too?
Mrballeng (author)  Mr.Sanchez1 year ago
It's stainless

Congrats on win and the succesfull campaign on kickstarter its a real honor to reply your creations.Thnx for share and please keep hammering and creating.
Really cool and congrats on your win! I'd wear this as a necklace! :)

Awesome job and congrats on the Kickstarter campaign! How are you going to mass produce them- waterjet?
Mrballeng (author)  Honus1 year ago
Thanks. We're still weighing the options between stamping, laser, and water jet. So many phone calls, but a great problem to have.
Once again, you've created something absolutely brilliant! Its useful, affordable, easy to construct (now that you've figured out the technicalities) and beautiful. It'd be awesome (& come in handy) attached to a parachord survival bracelet! It'd look decorative yet serve a very practical purpose. Its pretty unisex as far as jewelry design goes. I bet you'd turn a pretty nice profit if you attached them to survival bracelets and sold them as a set. I know I'd buy one for myself as well as a few extras to give as gifts.
Mrballeng (author)  gecko_girl31 year ago
Cool thanks. I've been trying to think up a design for a bracelet but it's still in the works. But while typing this I think I just got an idea. Thanks!
Please let me know when it comes to fruition. I'd love to purchase one (affixed to a survival bracelet). We do a lot of camping during the summer and these would most definitely come in handy (hanging a hammock, water jug, etc). It'd be especially handy if instructions were included so users could put it all back together should they use it. That way everything could go back to one neat little (stylish) bracelet.

I was also thinking a belt with several fish bones would be a great item for hardcore survivalists!
Mrballeng (author)  gecko_girl31 year ago
Good ideas! I'll be sure to let you know.

I want to invest in your company! Creative. Practical. Simple designs. Great instructables always. and so prolific!! I will go to your site and give you support!

You have also solved my "what do I give for Christmas presents??" This is perfect!

I also like gecko_girl3's suggestion re jewelry. I think I'll be wearing mine around my neck!! I happen to like fish VERY much.

Thank you for posting on instructables. Keep going man!!!! You are awesome!!
askjerry1 year ago
That is a successful design... simple, elegant, and fully functional. I think you will do very well with this... I expect they will show up in camping stores all over the place. I also suspect every hacker in a 5,000 mile radius will be making wooden ones less than an hour after reading this!

As usual... great job!
Damn, I swear McGuiver would have tried to make this with a paper clip or something! This is some truly great design!! Don't mean to be girly but it can be worn as a pendant, or on a paracord wristband, or a Keyring etc. when not in use, so you'll have it close at hand whenever it's needed. You've got my vote and support for sure
Congratulation on going past the supper stretch goal!!!
