I usually wear a thicker leash(it looks pretty ridiculous tbh) on larger days, but in no way could imagine it cutting my finger off. I wear a thicker one since I have had many snap on me before, and even on normal chest-head high waves. I do notice it a bit more, but it actually gets tangled up a lot less than a usual leash.

Have no idea where I bought it from as it is several years old but for those complaining about their leashes breaking you may want to look into it.
