Will & Finck Antique Tool -- Not a clue.

[geekeasy]

This tool came out of an estate sale in Orinda, CA. 

It labeled "Will & Finck, SF" and they made a bunch of nice knives during the Gold Rush.

Beyond that, I don't have a clue what it is.

More information about this mysterious find:  the black steel blades have very sharp points but no cutting edges.

Maybe for flax or wool?

[cody6268]

Perhaps something to do with the fur trade?

[Papaw]

Perhaps a carpet stretcher and cutter?

  is that a wooden block ? 

  with the very sharp points and no cutting edge, and them making sporting goods in the early 1800's
  I was leaning toward the same as cody6268 suggestion of fur trade.
   perhaps for stretching the fur on the drying/curing board.  the fine points would not destroy the hide.  9JUST A THOUGHT)

   Will & Finck, San Francisco, Calif. made and sold many types of items,  bowie knifes, cutlery, granite ware,
   gamblers card cheating equipment and sporting goods.
    Frederick A. Will & Julius Finck,  Fred was in business by himself until Julius got involved with him.

     in 1877, they received an award from the twelfth industrial exhibition in San Francisco, Calif. that was put on
     by the Mechanics Institute  for their carving set.

Found the answer.  It's an upholstery stretcher. 

The modern ones don't look too different:

Interesting. If I had to use that, I'd keep a good stock of band-aids close by.
