Plastic Bottle Cutter Card: Cordage and Rope Maker Tool
Turn Plastic Bottles Into Useful Cordage
The Grim Workshop Cordage Card is a reusable plastic bottle cutter and rope maker tool built around a simple idea: a common bottle can become a long supply of useful binding material.
The stainless steel card guides a prepared PET bottle past a small blade. As you pull and rotate the bottle, the tool cuts a continuous strip that can be used flat or twisted into thicker cordage.
At about 3.37 by 2.12 inches, the card body fits compact survival kits and tins. The assembled cutting hardware adds thickness, so this version is best carried in a pouch, tin, or pack instead of pressed into a wallet slot.
A Rope Maker That Turns Waste Into Working Material
Cordage is useful for shelter work, repairs, bundling, gardening, camp projects, and dozens of small jobs. It is also easy to use up.
The Cordage Card gives you a way to make more from material that is often already nearby. A smooth PET bottle can become one long strip instead of going straight into the trash.
The card format gives your hands more working area than the Micro Tool or Dog Tag versions. That makes it a strong choice for a dedicated cordage kit, workshop drawer, vehicle kit, or pack.
The result is lightweight binding material you can cut to length, twist, braid, or gently warm for tighter wraps around suitable projects.
From Bottle to Cordage in Four Steps
- Choose a smooth PET bottle and remove the label, cap, and bottom.
- Trim a clean starter strip so it can enter the cutting path.
- Set the spacer for the strip width you want.
- Pull with steady tension while rotating the bottle to create a continuous strip.
Clean preparation matters more than force. A smooth starter edge and steady pull help the strip stay even.
Use the strip flat for binding, or twist several strands when a thicker line better fits the job.
Cordage Card Tool List, Skill Guides, and Training
Every tool on this card is backed by a full skill guide.
That means you are not left guessing how to make cordage or use rope systems effectively. You can learn exactly how each piece works, when to use it, and how to apply it in real situations.
Each tool listed below links directly to step-by-step guides so you can build real cordage and improvisation skills.
This is part of how Grim Workshop works.
Get Better Results With a Little Practice
This tool rewards setup and rhythm. Start with a clean, straight bottle and practice on a few pieces before building an important project.
- Keep the starter strip smooth and even.
- Pull in line with the cutting path instead of twisting sideways.
- Maintain steady tension rather than jerking the bottle.
- Try different strip widths for different jobs.
- Keep spare blades and spacers with the card so the kit stays ready.
Cordage Card Size, Materials, and Carry
- Card body size: about 3.37 by 2.12 inches

- Material: hardened stainless steel
- Function: cuts PET bottles into continuous plastic strips
- Carry: best in a tin, pouch, workshop kit, vehicle kit, or pack when assembled

The card is reusable. Replace the cutting blade when needed and keep the hardware together so the tool is ready for the next bottle.
Put Bottle Cordage to Work
- Bundle loose gear and organize supplies.
- Make garden ties and lightweight plant supports.
- Lash poles for camp projects and practice structures.
- Create repair wraps for handles, containers, and gear.
- Make loops, tags, and hangers around a workshop or campsite.
- Experiment with twisting and braiding strips into thicker cord.
The value is not one single trick. It is having a compact way to make more binding material when a job appears.

VerifiedDoes not work very well. Have tried each possible configuration. Even tried sharpening and replacing the blade.

VerifiedGreat little cordage maker, works very well. Grand kids have fun helping make ,different colors of line.
John Lewis
VerifiedVery cool! I Purchased all 3 cordage making options. I'll be using them to make 3d printer filament from plastic bottles. I think the default width is a little narrow, fortunately they sell bushings to change the width of the cordage. I'll be buying a few of them next!

Verifiedworks well though even when following all instructions was hard to start rope
Mike
VerifiedMaybe the blade I got was dull? I've tried re-arranging the blade every way but it does not cut at all. I tried honing it on sandpaper too with no effect. I can only get inch long strips of plastic before it jams and I have to restart

VerifiedVery well thought out items
adel megherbi
VerifiedTried it as soon it arrived and was pleased. This tool will make it possible to make cordage from waste bottles to tie what ever, tarp, tie a chair, or what ever. Then spare your more pricey paracords for more important projects. Perfect doomsday diy tool.
