You can skin anything up to and inclusive of Deer with a SAK.

SAK's are much underrated as a survival tool. I carry a SAK alox Farmer or a Huntsman. For shelter building (and we are not building a log cabin here) and basic fire/trapping techniques they are more than adequate.

As for dispatching something that you have just snared or trapped? Probably not. But you can use it to carve a dinkum club.

Which will do the job.
