The folding Stanley blade holders are ideal,cheap,and easily loaded. I always have a DMT diamond hone about,so even these "throw-away" blades,can be easily dressed up,and increased use obtained.
I would not use a knife for SWA,as it nicks the wire coating,just where Mr.corrosion likes to start,preferring a Thomas Betts peripheral cutter. That's just a personal thing...
I have two Spyderco legal-carry drop leaf pen-knifes,one orange,for work attire,and a black one for other times.
I have a lovely Buck folder,ATS-34 steel,shimmed bearing,leather belt holster...but it got an issue with "entitlement",as it locks,so it only gets occasional outings.
I would not be without a knife,if at all possible,which after all the bad press,is merely a "tool".
Knives are not dangerous. That adjective is reserved for people.
Nobody calls spoons,dangerous,when folk start to get fat...
