question:  Why did Kalvin hesitate to share information about the new invention?
context: [Transcriber's Note: This etext was produced from Worlds of If Science Fiction, August 1958. Kalvin Feetch shrunk visibly. "But Mr. Piltdon," remonstrated Feetch unsteadily under his employer's glare, "don't you remember? Our own Piltdon opener barely manages to open a can in eight point nine without chimes. I want it completely developed, engineered and tooled-up, ready for production. "But Mr. Piltdon, four months is hardly time enough for development, even with an adequate staff. I've been trying to tell you for years that we're bound to fall behind because we don't have enough personnel to conduct research. A designer had to dream at his board, investigate, search, build, test, compare, discard. He had always wanted to devote all his time to research, but Piltdon Opener had not given him that opportunity. What had happened, to the proud dream he once had, the dream of exploring uncharted engineering regions, of unlimited time to investigate and develop? Ah, well, thought Feetch straightening his thin shoulders, he had managed somehow to design a few good things during his twenty-five years with Piltdon. Well, he had to start— "Chief," said Hanson a few weeks later as they entered the lab, "I'm beginning to wonder if the answer is in the hand mechanical type at all." "We must work along classical can-opener lines. Twenty-five years of your life you put in with Piltdon, and he'd fire you just like that if you don't do the impossible. The Piltdon Company is built upon your designs and you get handed this deal!" "Hello," said Feetch as an aproned machinist entered carrying a glistening mechanism. The machinist departed and Hanson locked the opener on a can. Several days later, however, Piltdon himself charged into the drawing room and slapped Feetch heartily on the back, causing him to break a pencil point. After Piltdon had seen it his eyes took on a feverish glint.
output:  He wanted to do more research into how it works.
options:  He wanted to do more research into how it works.  He wanted to be the one to tell Piltdon.  He wanted to keep the invention for himself.  He wanted to save his job.
