I'd be pretty sure the one on the right is ivory. The blade looks cut down, but that's ok.
What happened to the blade on the left one?? That looks a bit far gone to me, but maybe you can use it as practice for the other one.
Look at the picture REAL close and that ivory one has a BIG chip in the blade that is hard to see in the picture. I ended up with 2 other ivory ones that were less than $10 each. One's unbranded and the blade is one of my favorites ever and the other one i finished honing and working on last night i'll probably test it out later today. It's a FW Engels special.I was wondering who was bidding against me That ivory one looks pretty decent.
