The Official Online RBS 6 Nations Store is open. The store has everything you need to get behind your team during the RBS 6 Nations, plus the store is now fully stocked with a much wider range of rugby merchandise.
Hamilton, whose last appearance for Scotland came against Italy in the RBS 6 Nations in March, has won 39 caps for his country and Davies is hoping he can tap into that experience.
"I've been really impressed with Jim since I arrived this summer, his work ethic and commitment is without question,” said Davies.
“The kind of intense passion and energy he brings to the group adds to his qualities as a natural leader.
"He has a very positive impact on the players around him, he never plays at less than 100 per cent. He plays with his heart on his sleeve and is very serious about rugby and getting things right.”
Hamilton, who scored his one and only try for Scotland against Argentina in 2010, added: "The best leaders and motivators stand up in changing rooms in the build up to matches and demand the highest standards of their team mates.
"The best then get out on the pitch and produce those standards themselves, backing up what they asked of others by offering the very same. I know when I demand certain things of others I have to deliver them too.”
