My grandfather (father's father) passed away almost 30 years ago. Several years later, my brother an I were going through some of his "stuff", and I found this little pocket knife. IIRC, it was in with his fishing gear, and was rather dramatically rusted. I cleaned it with lots (and lots) of Naval Jelly, then buffed with my handy-dandy Dremel. Far from perfect, but much improved. Nowadays it sits in my desk at work, and gets occasional use as a letter opener. And a reminder of him...
It's pretty small, barely 2.5"... Flat Top National Bank is where he worked...
