Three men who attacked revellers at a birthday party with a machete, knife and a martial arts weapon have been jailed for more than 14 years.
Reid, Costigane and O'Donnell admitted their parts in the attacks
One guest was stabbed and needed a blood transfusion of 30 pints. Another had his arm broken in two places.
A third man was hit over the head with a martial arts baton.
Stephen O'Donnell, 19, Robert Reid, 23, and Michael Costigane, 24 all admitted their parts in the attacks in Glasgow's east end on 6 January.
The attack happened after O'Donnell's long-term girlfriend Jaclyn Grimes left him.
On 6 January, the teenager found out Ms Grimes was at a birthday party in Colinton Place.
O'Donnell and friends Reid and Costigane armed themselves with weapons and went to the party.
The court heard guests tried to stop him harassing Ms Grimes.
The gang then attacked Stephen Shaw, 39, who was hosting the party, and his nephews Steven and Christopher Haig.
O'Donnell broke Steven Haig's arm in two places and repeatedly hit his body with a meat cleaver.
He then used the weapon to hack Mr Shaw's arm.
Reid stabbed Mr Shaw in the stomach with a knife.
Costigane hit Christopher Haig on the head with a numchuck.
Mr Shaw's heart stopped three times as medics tried to save him.
He has since had part of his bowel removed and faces further surgery.
At the High Court in Edinburgh, O'Donnell admitted attempting to murder Steven Haig and seriously assaulting Mr Shaw.
Reid pleaded guilty to attempting to murder Mr Shaw while Costigane pleaded guilty to assaulting Christopher Haig.
All also admitted causing a breach of the peace.
Reid and Costigane were on licence after they were released early from previous high court sentences for assault.
Lady Dorrian sentenced O'Donnell to four years and 10 months in a young offenders' institution.
She also jailed Reid for six years and eight months and jailed Costigane for three years and three months.
