He spends most of his time with schist from Gibbston valley, but harbours a certain fondness for stones from Glenorchy as well, possibly, he says, because they are harder to get.
Probably, his leanings are not that unusual for a stonemason working in the Queenstown area, and this fishing guide and artist is one of about 50 making a living from working with rocks.
Fifty (working for up to 10 companies) may seem a lot, but there is still plenty to do, with an apparent endless stream of companies and individuals wanting stonework fences, fireplaces, walls and features erected around their Wakatipu properties.
Mr Edwards is installing a petanque court for his in-laws in between projects at the new lodge at the Branches, the QDL building in central Queenstown and apartments in Hallenstein St.
Queenstown, Mr Edwards says, offers the lifestyle and village feel he and many other outdoors worker-types love.
He gets to feed his passion for fishing, goes skiing in the winter and, on occasion, indulges his flair for the artistic in his work - something he gets immense satisfaction from.
It is a lifestyle he knew suited him down to the ground more or less from the moment he arrived in Queenstown eight or nine years ago on holiday.
He had spent the previous 10 months building sets in Wellington for the first two Lord of the Rings movies.
When the 22-year-old Englishman got the call to come to New Zealand to work on the movies, he was overwhelmed.
"I thought all my Christmases had come at once, to be honest. I borrowed the money to get here from my mum. I paid her back in three weeks, it was that good."
When the work ended, he decided to take a holiday in Queenstown, where he stayed, got a job with a stonemason and met local nurse Roz Nelson, with whom he now has two children.
When daughter Scarlett arrived about two years ago, his "ambition levels just went way up", and he decided it was time to strike out on his own.
It was a decision that surprised even him.
"Responsibility, for a small time, outweighs your maturity, it seems."
And running his own business has been good.
He found working on the Rees development one of the more satisfying jobs he has had, thanks to good management and a community conscience on the part of the developers.
Another project that stands out was doing the stonework on Geoff Turner's house on the Remarkables.
"I really liked that job because the place is standing so alone and the work was really nice. He was a really approachable guy, too."
Once or twice a year, he is given to doing the odd voluntary job restoring historic walls and buildings around the Wakatipu because they are "talking points" and he feels they should be restored for future generations to enjoy.
"It's good to get out there and it's something we can do while the kids run around in the forest for a few hours."
While business is still good, he is aware contractors in Queenstown are experiencing a slowdown as a reflection of the economic situation.
"It's just a cycle; it's part of everything. It's happened before and things always pick up again."
For him, Queenstown has been perfect, because, he says, it is a village that offers some of the things people would like from city living as well.
"They say it takes a village to raise a child and I love this community. It is so enclosed. Everyone knows each other and, I think, because of that, it polices itself well."
