Here's another solid brass tool to add to my loadout of adaptive hardware. I'm always looking out for tools that can help me adapt to my environment or supplement my resources, especially if normal resources are unavailable or scarce. This particular tool turns plastic drinking bottles into cordage!
You'd be pressed pretty hard to wander too far anywhere and not find modern trash. Plastic drinking bottles get thrown out of cars along roadways, get blown or dumped into waterways and turn up all over the place. The trick is to turn this abundant waste into useful product! Thats where a tool like the Cablelaid by Oceanus Brass comes in. Machined from solid brass bar stock, the tool is based around a simple principle; a razorblade, held in place behind a channel to feed the leading edge of the plastic through and cordage out the other side.
The top plate of the tool is held in place by three inset Alan key screws, to facilitate swapping out of the simple razor blade in the event it dulls, though flipping it would double your cutting mileage, before replacement or sharpening is required.
The tool has three channels built into the side that both guide the bottle in to the razor edge but also set the width of the cord produced. Notches set at 8mm, 6mm and 4mm to the blade with a 2mm guide slot along the top of the tool. The tool works by cutting the end of a plastic bottle off, then feeding the edge into the desired notch and the razor begins to cut the bottle into cordage. the notch then feeds the bottle in measured width to the razors edge and cordage exits out the back of the tool.
In order to maintain a constant pressure on the cutting edge and even bind-free cutting, it is beneficial to mount the bottle to the tool, such that it spools.
To facilitate this, the tool has a hole bored through it, that fits a pen, pencil or the purpose made telescoping feed rod, its also helpful to anchor the tool in place, and a couple of nails serve the purpose well. Thus braced, its a matter of cutting an even strand, which takes a little finesse, and more than a few false starts. The more even the initial cut of the bottle is the better the start will be. as notched cord is weak and often snaps as it is drawn off the bottle.
I found that gripping the end of the cord in some pliers made for a good method, allowing me to focus on keeping an even tension on the cord, such that an even cutting would take place, free from pinching and mis-angled cuts.
