Replacing a wire in Hercules and Caterpillar soap cutter


Uh-oh, your wire snapped?

Don’t worry — that’s totally normal! It happens over time, thanks to something called steel fatigue (basically, the wire gets tired from doing its job over and over until it just gives up). Another possible reason for a wire snap is overtightening the pegs or your soap just way too hard. If you deal with hard bars, use a thicker wire or reduce curing time.

Tools and materials you will need

You probably already have a spare wire lying around — we include one with every cutter we ship (most of the time... hey, we try our best 😅).
If you’re out of spares, no big deal! Just grab a .022 gauge guitar string.
That’s the sweet spot we recommend — strong enough to last a while but still gives you a nice, clean soap surface. If you go thinner, you might get a glassy finish, but the trade-off is they snap faster.
You’ll also need a wire cutter and regular pliers to help yank the old wire out, but it can be removed with bare hands. Any cutter will do—nothing fancy is needed.
Got your string and tools ready? Awesome. Let’s get that cutter back in business!

The wire replacement process

Begin by removing the old wire. Carefully unwrap it from the peg and pull it out, taking caution as the wire tips are sharp, which may cause cuts. Additionally, be mindful not to scratch the handle, as we dedicated a lot of time to crafting it, and any scratches would be unfortunate.

Now let's install a new wire measure and cut a piece of wire that is 22'' or 56 cm long. Turn each peg to get easy access to the hole in the tuner pin. Take one end of the wire and insert it through the hole (the wire should extend about 3/8-1/2'' beyond the pin.
