Caliber	7.62x17 Type 64
Weight, empty	0.69 kg loaded with sheath
Length	265 mm
Barrel length	89 mm
Capacity	4 rounds

QSB-91 shooting knife was developed in China during early 1990s, and is in use by special elements of PLA and Chinese armed police.

QSB-91 is a fixed blade combat knife with round hollow handle, made of metal. Inside the handle there are four fixed 7.62mm barrels, pointing toward the blade (two barrels at each side of the blade). Each barrel is reloaded separately from the breech, once the screw-on end cap is removed. The end cap contains a rotating striker, which turns 90 degrees before striking next primer every time the trigger is pulled. Trigger is placed at the front of the grip and doubles as a guard for the knife. Trigger unit is of double action only type, with relatively long and heavy trigger pull. Fixed sights are located on the grip, at roughly 11 o’clock position when looking from the rear. To fire the built-in gun, knife must be removed from the sheath, loaded and pointed to the target, blade first. Once sight is acquired, trigger is pulled up to 4 times, each time discharging one barrel. Apparently, QSB-91 knife cannot be fired with sheath on.
Type 64 pistol ammunition is of conventional type, based on the 7.65x17SR Browning / .32ACP cartridge, but with rimless case. Therefore, unlike practically noiseless Russian NRS shooting knife, QSB-91 shooting knife is far from being quiet when it is used to shoot at the enemy. Claimed effective range when firing built-in barrels is stated as 10 meters.

1. Descriptions of RF Receiver IC CMT2210AW:

The CMT2210AW is an ultra low power, high performance, low-cost OOK stand-alone RF receiver for various 300 to 480 MHz wireless applications. It is part of the CMOSTEK NextGenRFTM family, which includes a complete line of transmitters, receivers and transceivers. 

An embedded EEPROM allows the frequency, symbol rate and other features to be programmed into the device using the CMOSTEK USB Programmer and RFPDK. Alternatively, in stock products of 315/433.92 MHz are available for immediate demands with no need of EEPROM programming. 

When the CMT2210AW is always on, it consumes only 3.8 mA current while achieving -114 dBm receiving sensitivity. It consumes even less power when working in duty-cycle operation mode via the built-in sleep timer. The CMT2210AW receiver together with the CMT211xW transmitter enables an ultra low cost RF link.

Ok guys, back again...I was wondering about this Tanner Krolle cover gun mechanism on the suitcase lock system (that by the way is carried by Saudi Arabia King, and good british royals) and this is the mechanism...of course on miniature

The Blish Lock is a breech locking mechanism designed by John Bell Blish based upon his observation that under extreme pressures, certain dissimilar metals will resist movement with a force greater than normal friction laws would predict. In modern engineering terminology, it is an extreme manifestation of what is now called static friction, or stiction.

Breech-closure for firearms.

Ok. IED's scanners are based on colour contrasts, of course besides not beeing able to disrupt the electronic detonator, I told you about yesterday, There's another, and as much important as the electronic disruption, the scanner machine from the "system" on not determine what is inside the bagage. And it is, its as simple as this, using old ray x films, covering the explosive.

Elsa David I've been on the IED's vulnerabity long time ago, and I studied everything about it

Elsa David this works anywhere from airport scanners to street scanners...

Elsa David the best way to use explosives, like old good terrorist groups know how, is on garbage containers, but also on swor on the streets next to the passage of the jerks
