John Wesley Powell pocketknife

 Powell as captain of battery F of the 2nd Illinois artillery took part in the battle of Shiloh, losing his right arm at Pittsburg Landing. He is most famous for being first down the Colorado River thru the Grand Canyon.

No idea if he had a pocketknife like this but it was the one thing I retained from my ex until losing it on a nightstand in Yosemite, it must have slid under the lamp base.  Took me a while to find it at Woodcraft and bought a replacement.

One blade opens incredibly easy one-handed, you just have to remember not to carry it on planes or any music or sporting venue that does metal detection. I should have gotten purchase information on that from my therapists to do all the ADLs I was used to.

The left blade is the one you grab with your thumb and finger, then set the base of the knife against your hip and it pops open.

The blade completely open, the other standard blade I barely use, too hard to get open. Friends dislike this because the blade is so sharp which I consider necessary since any sawing motion with a knife is nigh impossible one-handed.
