Marked "PAL RH-36 Made in USA" fighting knife.  Purchased from an estate sale. 
Stacked leather handle. 
 
Blade is 6 1/2" long.  Total length is 11 1/2".  I think it is Vietnam era but could be older.
 
Usual condition for an vintage/antique knife.   No missing leather stacked pieces on handle.  Somewhat loose guard.  Signs of age on blade.  OVERALL GOOD CONDITION FOR ITS AGE.  STILL STRONG.  THICK SPINE.  SEE PICTURES.
 
PURCHASED AT AN ESTATE SALE OF A MILITARIA COLLECTOR.  PLEASE SEE MY OTHER MILITARY ITEMS.  I WILL PROVIDE A DISCOUNT IF YOU BUY MORE THAN ONE ITEM AT A TIME.
 
I believe this is WW2 but could be post.  Please use your best judgement.
