The vintage Kutmaster stacked leather handle fighting knife, particularly those made around 1944-45, is a notable piece of militaria due to its unique combination of features from the M3 Trench Knife and the USMC/Navy MKII Fighting Knife. While not officially issued, these knives were privately purchased by servicemen during the later stages of World War II, likely for use as a more readily available fighting knife. They are recognized for their 7-inch blades and stacked leather handles, often found with a nickel-plated finish and paired with a leather sheath.
