A SWORD and punching attack from an enraged ice user left an amputee trying to crawl away when his prosthetic leg fell off.
Men delivering motorbike parts came under attack from Kingaroy's Shane David Langhans in April this year.
Brisbane District Court heard Langhans, 36, punched one man in the jaw.
That man fell down and his prosthetic leg fell off.
"He tried to crawl away and you struck his left shoulder with a sword,” Judge Paul Smith told Langhans on Thursday.
The man with the prosthetic leg managed to climb over a fence but Langhans chased another victim down the street, swinging the sword.
One of the attacked men was flown to Toowoomba Hospital for surgery.
The court heard police found "swords and machetes” at Langhans's address later.
Langhans faced one charge of common assault, one of causing grievous bodily harm and two of wounding.
The court heard drugs, especially ice, were linked to many of Langhan's problems.
"It makes people violent doesn't it?” Judge Smith said.
"You're lucky the injuries weren't more serious.”
In custody since the attack, Langhans had become a workshop supervisor, which impressed the judge.
Langhans also earned some credit for an early guilty plea.
Judge Smith said Langhans still had a chance for rehabilitation.
The court heard Langhans had not used drugs since being in custody for the attack.
And he had made progress reconnecting with supportive family members in the Caboolture area.
Langhans told Judge Smith said he had done a relapse prevention plan in jail.
"I don't want to throw away the key just yet,” the judge said.
"If you get out, get a job, stay off the drugs and get some treatment for it, you might have a chance.”
Langhans was jailed for four and a half years.
He had already spent about six months locked up.
He will be eligible for parole in December 2018. -NewsRegional
