Helen Rae, 45, and co-accused David Wilson, 41, pounced on Alana Michie and Paul Brown at their flat in Glasgow’s Drumchapel on April 19, 2024.
Wilson and Rae, of Clydebank, entered the property while their victims were out.
On their return, Miss Michie had her wrists tied with shoelaces while Mr Brown had a knife ran down his face.
Mr Brown was also told that he was going to be put in a boot then dumped in the River Clyde.
Wilson and Rae previously pleaded guilty at Glasgow Sheriff Court to abducting Miss Michie and Mr Brown.
Sheriff Andrew McIntyre sentenced Wilson to three years behind bars and he will be under supervision for one year upon his release.
Rae has now been ordered to do 300 hours of unpaid work and put under supervision for 18 months.
The court earlier heard that Wilson and Rae were long time friends who knew their victims from living in the local area.
It was stated that there had been an ongoing feud over “property.”
Miss Michie and Mr Brown returned home on the day of the incident to find Wilson and Rae inside in possession of weapons.
The two victims were ushered into the living room and instructed to sit on the sofas.
Prosecutor Lauren Aitchison said: “Rae slashed Miss Michie’s jacket she was wearing using nail scissors.
“Her hands were then tied using shoelaces.
“Wilson meantime brushed a blade down the cheek of Mr Brown saying he was going to slash him.”
Rae also punched Mr Brown to his head and body before Wilson struck him with a mug which caused a bleeding injury.
Miss Aitchison said: “Wilson stated that he would take Mr Brown away to the boot of a car and throw him in the River Clyde.
“Rae told Mr Brown to give Miss Michie a kiss as he will never see him again.”
Wilson led Mr Brown outside at knife point leaving the two women inside the property.
Mr Brown was able to escape after Wilson went onto his mobile phone.
The victim approached a member of the public for help and contacted the police.
Officers later found the two women in the property and Rae was arrested.
She later claimed: “I didn’t do it.”
Wilson was unable to be traced initially and he later handed himself in to a police station two days later.
Gerry Devanney, defending, told the sentencing that Wilson’s electric bike had “gone missing” before the incident.
The lawyer added: “His intention was to go and ask questions about that in hope that he could retrieve the bike.
“He didn’t go armed to the address. His intention was not to get involved in the way that he did.
“The response he received was the bike had been sold and matters escalated and then he became involved primarily with Mr Brown.”
