It's happened to all of us. We're skinning a deer, and the darn knife gets dull halfway through the job, and we end up just muscling our way through the job, mangling meat as we go.
There is no sharpening stone, steel nothing. You probably just rolled the edge of your knife over, but it doesn't matter if you don't have anything to straighten it!
I'll give you a little tip that works so well, you might just prefer it to many other sharpening systems. It's usually with you, and mere feet away from the deer you are wrestling with.
Simply walk over to your truck, roll the window down half way, and use the edge of the glass as a ceramic sharpening edge. It works really really well.
This trick was taught to me by one of my best friends. He is paralyzed from the waste down, and his truck is his life. I gave him a spyderco endura years ago as a birthday gift. He used to have me sharpen it (I'm a trained knifemaker and sharpening things is what I do). but then he learned this trick and showed it to me.
Been using it for about 2 years now, and I can honestly endorse it as an excellent alternative!
I actually prefer the edge that this method puts on the knife, for butchering deer. It gives it a lot of "bite".
Give it a try! I guarantee that you will wonder why you never heard or thought of this before.
Hopefully, this will get some of you fellers out of a jam this year at deer camp.
Good hunting!!!
