This is a reed cutter from Reed Machines. It works for both oboe and English horn reeds. The guillotine style allows for straight cuts. I believe the purchase price was around 50,000 to 60,000 yen (though I don't remember the exchange rate...). I used it a few times and then stored it at home. There's nothing wrong with the product itself, but I own multiple reed cutters and don't anticipate using this one in the future, so I'm putting it up for sale. An unused spare blade is attached to the back (see photo 3).
