Looking at it the main blade it almost looks salvagable as it is with some minor fixing. Wharncliffe?? Not sure I could point it without getting into the nail nick but a sheeps foot maybe.
On the smaller blade. Not sure it would function really well as a screwdriver. It depends on how thin the edge was and on those smaller blades they were thin on those especially toward the back.
Its such a shame. Nice looking scales from what I can see. Robeson had it going on compared to other companies in their day. I'm sure its got nickel silver bolsters also. They were high quality makes that ruled in their time IMO. I sure love those old easy openers. Its always been my favorite pattern. They ride great in the pocket, and are quite secure in the hand also.
It would be a good candidate for a parts knife for someone looking to put two good blades into a good handle using original parts. It looks like the body is still in good shape. I imagine the back springs are still good to go??
You maybe would be better off to post this on Dirk's forum here (link below) and see if one of the guys that I refer to when I'm swamped and don't want to take on more slippies that put me behind. Several of the guys over there at his forum have a pretty fair amount of spare parts from some batch purchases they made on ebay for multiple knives and they prefer and really specialize more on slippies work. One of em might have a blade that could replace one or both if you are lucky. Its a shame to let such a classic stay that way.
Go over and talk to Bob Picklesimer and Muskrat man or a couple of the other guys that work a lot on the old slippies and touch base with them about what they might have floating around in boxes. If all else fails I can probably muster something for you yes but I'd try that first if it were mine. Start a thread and tell em I put ya up to it.
