An artist for nearly seven decades, Satoru Abe still spends seven days a week in his art studio at home in Kaimuki, creating new works.

Abe’s new copper sculptures — “Compositions” 1 through 15 — are on display as part of the “Across Generations” exhibit presented by the Friends of Hawaii State Art Museum at the Artizen Cafe Gallery through Feb. 24. The miniature copper sculptures reflect Abe’s signature treelike forms and ethereal, circular wheels, but in new combinations.

“Across Generations” showcases the works of three generations of Hawaii artists — Abe, 90, Hamilton Kobayashi, 65, and Kainoa Gruspe, 21.

Abe groups various elements of his sculptures to create novel compositions. All of it is hand-cut, taking hours to complete. The artist said it is a sort of meditation for him. The McKinley High School graduate works on four to five pieces at a time, following his intuition to reach the final result. The variations are endless.

“I think I have found something new or different that has never been done,” said Abe. “I surprise myself when I finish.”

Abe, an abstract sculptor and painter for 68 years, is known for his singular forms, which grace the grounds of the Spalding House in Makiki, Honolulu International Airport and the Hawai‘i Convention Center.

To be original, Abe said, one has to take risks: “That’s what creativity is about, doing things you’ve never done before.”

Kobayashi, a longtime friend of Abe, is also unveiling some new works, including the painting “Makapu‘u Shoreline,” in addition to a volcano series.

To support his family, he had given up painting to run a framing business but was inspired to return to art by Abe.

With his abstract paintings, Gruspe, an art student at the University of Hawaii at Manoa, explores boredom and apathy using a mix of materials, including house paint and oil on canvas and reclaimed frames.

All the pieces are for sale, priced between $150 and $7,000.
