Sometime back I purchased Model 12 Explorer with whistle and tick remover both built into the handle,

It is quite LARGE basically too big for pocket carry,so I had Kris Kravitt of Tree Stump Leather up in Maine make a nice belt sheath for it.

Typical Opinel quality and instead of a beech wood handle it has a composite handle that will not swell up if it gets soaked in water.
