Hello.

Negatives.
Very expensive. Whatever it is, the bad has been done with the increased prices.
Positives.
The knife is extremely high quality, I don't think it will ever break.
The fabric strap is strong, I have put 5 kilos plus a knife and you can feel its sturdiness. I also don't think it will break.
And if you try to cut the fabric with a knife, you can't with a simple knife.
It is huge in length to fit everyone.
You cut it to your size and you are ready.

I hope I helped.
