I think you are making a good choice with the Coffin Jack. I LOVE mine. I also really love my two Eureka’s, but I had to smooth my secondary blade side on one of them just a bit, b/c it broke skin a couple of times. After that, they have been perfect knives.
I’m actually going to thin my Case Bose herd a bit. My Coffin Jack, two Eureka’s, and Cattle Knife are staying, but I’m going to let my Stockman, Lanny’s Clip, and Wharncliffe Trapper go. I just don’t have the room to keep them all, if I’m not using them.
I know it’s never happened to anyone on this forum before,

but I went in a little hot to collecting traditionals, and really need to pare back! Of course, I’ll still be looking for a Wharncliffe Whittler, b/c I am weak.
