Anyone know what this is?

Hi to all. My first post, so be gentle. I got a really good deal in an auction, a Kennedy 7 drawer machinist tool chest filled with someone's leather working tools. I got over 75 vintage Craftool stamps which more than covered what I paid for it, OK , you dragged it out  of me......$80. I have id'd everything in the box except this thing. No markings, green painted wood handle. Any ideas? Thanks.

Never mind, guys. Found out it is an old style glass cutter for round glass tubes. Thanks to everyone who looked though.

Actually, it is a combination knife sharpener and glass cutter.

Thanks, how is it supposed to work?

The small blade off to the side is the glass cutter. To use as a knife sharpener, you draw the blade perpendicular between the large round wheels. Rotate them once in awhile to present fresh sharpening edges. These work fairly well on certain blades made of carbon steel.

OK. Thanks for your info, you learn something new every day.
