Picked this up at a thrift store. Probably paid too much (much cheaper on e-bay). I have some questions. What does SCProm-16-13S mean? Is that a model number. It is on both blades. There is no made in label anywhere. What's up with that? Any other comments on these would be appreciated. I did a general search on the internet and had lots of hits for sets like this but most had wood handles, only one had handles like these and they weren't the same knives.
