How do I cut swa cable using hand tools?
Swa cable can be very difficult to cut when first starting, especially if you don’t have the correct tools we recommend using a junior hacksaw with a fine tooth metal blade. This should make the job a little easier as the teeth of the blade will not get stuck and stop you in your tracks, try to keep steady and the cable still until you get around half way through, then bend the cable over so that the cable opens and does not grip the hacksaw blade as you are cutting the cable.
