Paul Roderick Fowler, of 1130 Renfrew Road, is alleged to have taken a hammer to Robin McConnell's head in the charge.
He's also facing a charge of assaulting Nicole Fowler, and uttering a death threat to both her and McConnell.
Fowler is also charged with carrying a weapon, a hammer, for the purpose of committing an offence and careless storage of five rifles.
During his court appearance in Truro on Wednesday, Fowler's case was adjourned until Thursday at 9:30 a.m. in Shubenacadie.
Crown attorney Paul Drysdale requested the adjournment be until Monday, as a key crown witness is not available on Thursday to appear.
Judge Warren Zimmer dismissed Drysdale's request because Fowler has been in custody since Dec. 31, however is leaving it up to the courts in Shubenacadie as to whether or not they go ahead without the key crown witness on Thursday.
Fowler was arrested Monday morning after police were called to a Renfrew Road residence at 8:30.
RCMP have said a 50-year-old man had been attacked with a hammer and a woman was assaulted when she tried to intervene.
Both victims sustained non-life-threatening injuries.
According to police, Fowler has served as president of the Hants County chapter of the Bacchus Outlaw Motorcycle Gang, but they aren't sure if he is still affiliated with the gang.
