New bayonet saves U.S. cool million

Two Arsenal Island engineers took an age-old weapon and figured out a way to save the taxpayers about $1 million.

The bayonet, a rifle-mounted knife designed to impale enemy soldiers, has taken on a new look.

In an age of supersonic bombers, nuclear weapons and other high-tech weaponry, it’s easy to forget that weapons as brutal and simple as bayonets are still used.

The knife refined by John Kreider and Loren Brunton is designed to be carried by elite military units such as the Army Special Forces or Rangers.

The improved M-9 bayonet differs considerably from its predecessor.

The most obvious difference is that it lacks a long, deep groove on the blade.

“The blood groove is there to eliminate suction,” Kreider said. “You see, when you take a cold knife and stick into a warm body, it can be difficult to pull out. But we determined that this bayonet would leave a big enough hole that there shouldn’t a prob-lem with pulling it out.”

A study Buck Knives conducted involving freshly killed antelope was used to reach this conclusion.

Besides eliminating the groove, the engineers added several other cost-saving measures such as using cast parts instead of brazed ones and eliminating several webbed straps for the scabbard.

These changes reduced the cost of manufacturing each knife by $9.38. With the Army buying 105,000 of the weapons at cost of $37 each, the design changes saved the government about $980,000. But the changes don’t stop there.

The new blade is black and a screwdriver attachment has been repostioned on the scabbard. Rather than have a gray metal blade, soldiers said they preferred a dull finish that wouldn’t reflect light and reveal their position as easily.

The screwdriver located on the end of scabbard was moved because paratroopers complained about being jabbed in the leg when jumping from aircraft.

Bayonets are more likely to used for cutting wires, probing the ground for land mines or cutting branches than as a hand-to-hand combat weapon, Brunton said.
