The fish scaler and scissors are in my opinion totally useless in a survival knife.
I use fish scaler all the time. Put the Champ into plastic bag, cut a hole with fish scaler and ... I damn scale the fish.I have no other tool at home and I don't do fishing. But what are going to do if your order fresh fish?I am happy with the tool, it does what it is supposed to do and I am glad they include it.I have never ever used the saw and the chisel though.
Having the knife in a bag with a small hole cut in it to push the scaler through, thus keeping the body of the knife clean, is genius.
