The surgeons of the 4077th need a special kind of instrument to perform a difficult operation on a casualty, and soon produce the new vascular clamp; meanwhile Corporal Klinger works hard to find Margaret's missing wedding ring after he accidentally throws it away.
Full episode summary
Hawkeye is frustrated at trying to perform a tricky arterial operation without the proper tool...a vascular clamp that is delicate enough to hold an artery without crushing it.
The surgical staff decides to try and devise their own specially-made clamp, first by asking he Army Engineers. Whey the engineers turn them down, they try and make it themselves, but Hawkeye and B.J. are mechanically inept (it doesn't help that Winchester tags along just to sit and laugh at them).
In the Mess Tent, Sgt. Zale says he's a "master craftsman", and can make one himself. After some initial skepticism, they put him to work.
A day later, he produces his clamp. Hawkeye and B.J. test it out, but when it grips itself too tightly on Hawkeye's hand and can't be dislodged, it proves a failure. Zale, hurt, storms out, and Hawkeye and B.J. are back at square one.
Hawkeye, desperate, offers up the Army Engineers a bunch of the 4077's nurses as "guests" for their next unit party (B.J. is horrified), without checking with them first. They then have to go to the nurses and ask for this huge favor, but the nurses turn them down cold, explaining that the engineers are "animals." On top of that, they're exhausted from all the work Margaret is throwing at them--she's in a foul mood ever since Klinger lost her wedding ring, tossing it accidentally in the trash.
A Korean merchant named Mr. Shin (the legendary Keye Luke) comes by with his cart of hand-made items, and he mentions that he has a ring that bears a striking resemblance to the one Margaret had (its a cheap ring with an even cheaper diamond setting, typical of Donald Penobscott). They commission him to put in the original inscription and get Klinger off the hook.
When they notice some of the other custom-made stuff, they also ask him to try his hand at the new clamp. He offers them a deal on the clamp, since they're buying such a crappy ring.
A few days later, Klinger tries to pass off the new ring as the original, but Mr. Shin messed up the inscription, tipping Margaret off. She thinks its a joke on her expense, but Klinger tells her they were just trying to make her happy.
In surgery, Hawkeye breaks in the clamp with a patient with a crushed artery--and it works perfectly. The surgery goes off without a hitch, and the patient's leg is saved.
After showing off the clamp to the patient, they notice there's an inscription--"Over Hill, over Dale, Korean Clamp will never fail."
