My thinking is that Dr. Mudd and Moodino have hit the nail on the proverbial head. I carry a Vic Tinker in the right hand pocket of my Key bib overalls and a Opinel carbon # 8 in the plier pocket. It's not big deal when the blade gets a little snug, just give the handle the "knack" like the instructions tell you to do and the blade pops out readily.....at least enough to get it out the rest of the way with the nail nick. I love the carbon steel that darkens with use and takes that wicked edge that the Opinels are famous for. When it dulls from prolonged use, a few swipes on a smooth steel and it's back to shaving sharp again with no abrasives required.
I have gutted three Nebraska whitetails with mine when I forgot and left the Morseth back on the seat of the pickup. It worked just fine. It's still the one I use quite a bit for the bung-hole cut and the initial ripping cuts down the legs and up to the throat in the hide. It's light and I'm used to having it in my hand all year long so it just feels the most natural when making these initial opening cuts. It'll usually still shave hair when I'm done with the job (much to the amazement of my hunting companions), I might add! I find that I use it quite a bit in the skinning and caping process, too. It's just the right size and the design is perfect for these jobs.
I'm 59 years old, an old deer hunter and an older Eagle Scout. I farm for a living so when a tool that has lasted a long as the Opinel design has on the world market, I listen. There's got to be a reason it has remained as popular an item it has over the years. In short, it is a tool that works the way it is supposed to at a fair price.
