Multi stove

I got a naturehike multi stove as shown in the picture. After I used a few times, some steel wire come off and could cut my hand badly. (Hard to see in photo). I wonder if the more expensive brand has this problem too? Or those are bronze to have some wire out as they were bent while storing in a box?

If you have used a multi stove for a long time and does not have this problem, please share with me. I want the stove to be able to use camping gas and kerosine.

Cheers

Thank you
