Raft Guide April-Sept. for the past nine years:
Strapped to my PFD are a Benchmade "8" Rescue Hook
CRKT Neckolas
I've carried a Lg Seb, Strider SnG or Spyderco Military in a PFD pocket for most of that time as well. I take it out after every trip & simply towel dry after every trip & have never had a prob with rust.
One time I accidentally left a Lg Seb clipped in waist band I lost it in "Big Drop" on the Arkansas River!
Carpentry the rest of the year:
Lg Seb or latest acquisition. &/or a med. fixed (ESEE3, CRK Nyala, Strider MFS).
