A woman allegedly inflicted knife wounds to her lover as she tried to shield herself from attack, a court was told on Monday.
Stephanie Brodley, 29, is also accused of trailing the other woman by the hair around her north Belfast home on Saturday.
Brodley, who is from Glasgow but currently of no fixed abode, is charged with assault occasioning actual bodily harm and possessing an offensive weapon with intent.
She also faces two counts of criminal damage and assault on police.
Belfast Magistrates' Court heard she allegedly carried out the attack at her partner's apartment off the Antrim Road.
A PSNI constable said the other woman claimed she was woken in bed by Brodley screaming and shouting at her.
"She trailed her about by the hair and threw her about the flat," the officer alleged.
Brodley then allegedly slapped her about the head while holding a knife.
The woman raised her hands over her face, according to police, but ended up with a stab wound on her arm which required 10 stitches.
District Judge George Conner was shown photographs of what he described as "a very significant injury".
During her arrest Brodley allegedly kicked a police officer and caused damage to a PSNI car and a second vehicle.
Defence counsel Neil Moore accepted his client had travelled from Scotland to live with the complainant.
"She's been in Northern Ireland for about a month," the barrister said.
Mr Moore confirmed his client denied the charges, and described the couple's relationship as "toxic".
Bail was refused due to the risk of further offences and concerns Brodley could flee.
She was remanded in custody to appear again by video-link on June 29.
