I picked up this leather sheath for my Explorer or Deluxe Tinker for $1. I saw the Vic logo but no other markings and figured is was a homemade deal. It's decently made regardless and my SAK fit perfectly tho theres a decent amount of space once the flap is closed. My Explorer is very snug so I don't think it will come out especially once snapped closed.
As you can see my Helmsman also fits, it actually is a perfect fit. I don't carry my Helmsman much but its nice to know it could fit. Not much thicker of a SAK than Explorer or Helmsman fitting in this sheath.
Anyway though I'd share.
