I have my grandpa's Randall model 1-8 in a HH Heiser sheath. He was in the service from 46-77. I was hoping to figure out a little more information about it. The sheath is missing a snap and the stone is gone. The blade is in ok shape. Would it be bad to clean it up and use it as a camping/pack knife or better to keep as is? If better to keep it as is I would likely have a shadowbox made for it and his 1911.
