This is a Jitte, an antique weapon. I received it from a family member. I was told it was purchased 20 years ago for 50,000 yen and is from the Edo period. I am a complete novice when it comes to antique art, but just looking at it makes me feel the history. Please see the photos for details. If you have any questions or would like additional photos, please contact me via the comments. Size: Length approximately 51cm Blade tip 34cm Thank you for viewing.
