Found this knife in my Grandmother's collection. None of us can figure out what the semi-circle shape and slots are for (see attached picture). Anyone have any ideas?

    How sharply cut are the slots? I have seen multi-purpose tools with slots like that to be used as peelers/graters. The bottle opener at the hilt would also suggest a strange multi-tool. Jul 18, 2017 at 21:45
  • @sobachatina, the slits aren't sharp at all, they're quite smooth. I guess multi tool makes sense, but I have no idea what the rest could be used for.

  • Is the spine sharp, making it usable as a mezzaluna? Jul 19, 2017 at 8:26
  • @rackandboneman No, the spine isn't sharp. Good question though.

  • If the metal is tempered right to support a serrated edge well, it will probably support sharpening the spine ;) Jul 19, 2017 at 14:28

It is a multi-tool, which appear to have been given out as novelties. The bottle opener and serrated knife are obvious, the slits are there to act as a pot strainer, the semi-circle shape and flat surface allows you to hold it against the edge of a pot and pour out the liquid while keeping solid bits in. I found a few of them on Ebay, the good links (as of this answer) are:

Vintage Farmers Co-op Creamery 1967 Bread Knife

Vintage Multi-Purpose Knife Bottle Opener Strainer Stainless Wood Handle Japan - Given the nature of Ebay I can't guarantee these links will be good for long

According to the inscriptions on some they were given out by a couple of different Farmer's Co-ops and a Drilling company...does yours have any writing on it?

...and here is a picture of a pot drainer (single purpose) as it would be used.

  • Ahhh, a pot strainer. That makes sense. We tried a Google image search, but that failed. Guess our Google-fu wasn't as strong as yours! It does have writing on the side, it says "Keller Grain and Feed."

  • As a 'novelty' item, I would not expect it to work particularly well. On the other hand it looks like you could get $14.95 off of Ebay for it if you want.
