You could make your own but the real fix is get a strimmer with a
cord.

I've got one. You go 5 meters and the cord snaps.

I did wonder why the cords are made of cheap plastic and not Kevlar which is
used for bullet proof vests and is exceptionally tough. You can buy Kevlar
thread so perhaps I'll try one day. The problem is that you need ceramic
shears to cut kevlar easily ;-)
