Tacticool concept: Pistol Bayonet Folder

I believe many of you still remember the pistol bayonet that Kabar made several years ago. It was a small fixed blade knife that can be attached to the Picatinny accessory rails on pistols. It was a novelty and a practical joke from the beginning to end. Though I didn't take it as big a joke as many other people. I think a compact knife that can be attached to pic rails can have its interesting niche.
Most gun people will say why even bother with such ridiculous concept? You should never need a bayonet for a pistol. I agree on the most part, but situations will come when a firearm user finds himself in a close range situation when firing a round is not the most viable option, either due to firearm malfunction or unable to acquire clear line of fire. Muzzle strikes, though mostly effective, will induce further malfunctions or even damage the firearm.
One the other hand, the main drawback of the most previous pistol bayonet designs is that they are usually small fixed blades that will interfere with holstering, and also they are usually too small to be carried as an easily accessible tool. The Kabar ones didn't even come with any real sheath, just plastic scabbards to cover the blades, without any carrying option.
However, if the design can be implemented into a folder, then these issues will be solved. When folded, the bayonet will be no larger than a flashlight and can easily fit into a holster that accommodates pistol lights. If not needed, then it can be taken down and clip to the operator's pocket just like a normal folder. Integrating the pic rail attachment mechanism into a folder's handle shouldn't be that hard, and modern lock systems like a frame lock will provide sufficient strength for its purpose. It can even be made into a switch blade with the actuate switch on the bottom so the user can launch the blade with the trigger finger.
Just some crazy ideas. I always believe a military rifle is incomplete without a bayonet attachment, just in case the soldier ran out of ammo or the gun ceased functioning. Since most people carry pistols(if they are allowed and choose to do so), then I believe a functional folder that double functions as a bayonet for their firearms shouldn't be too ridiculous, right?
 
The gun/knife/bayonet concept is an old one. I have a British flintlock pistol with a folding bayonet that dates from the early-mid 1800's

You are right, but this concept never got its chance and remained a novelty. I just think it is worth a revision.
 
I think I recall seeing a while back a book devoted entirely to the concept. It was called Guns and Blades (I think). There were many variations from several different countries.

The concept has been used quite a few times through many years - not least in the 'Apache' revolver.

There is a reason, that it didnt take.
 
I had one of those Kabar gun bayonets, while they were on sale for $15.
Knife quality was good, fitting system not so good but, overall... It was one of the most dangerous attachment I've ever put on a gun.
I quickly got rid of it.
It's just like you're begging to puncture yourself or chop your own finger.
While it was looking good on the gun, it was indeed a terrible idea.
And if you put a folder up front... the opening of the blade might be an issue with a regular system, and bulky with an OTF.

They have been coming up with stabby pistols since they first came out with pistols. The problem with all of them is that they are just not that effective or useful. You are never going to have the kind of reach that just carrying a larger blade is going to give, and it sacrifices the speed and maneuverability of the smaller blade by adding a pound or more of weight. Even in the age of single shot pistols, using the empty pistol as a bludgeon was preferred to turning it into a clumsy and relatively fragile combi-weapon. The space and weight of the extra knife could instead go towards another magazine.
 
I think it could be very useful.
You could roast marshmallow as you were waiting for your turn at the range or as a one tool option for hunting/cleaning game.
 
Figure the PLA's NORINCO 80 was a combi gun/blade fantasy come true.

The need for a less complex solution
have seen the feature as an index finger hole (much like that on a karambit)
Put to good use in the design of a slim and compact bladed weapon
Which allows for the trigger finger to execute both...

I have the SOCP dagger, and it is not comfortable to hold in the weapon hand while trying to reach for the trigger. Not to mention it interferes with mag change. It is a fantastic off-hand back up weapon though.
Putting a blade weapon on a firearm that needs to be drawn out like a conventional fixed blade is a different concept that I am also quite interested, but not really a bayonet.

If the folding bayo attach to the pic rail under barrel and can still be easily fitted into a holster, then it will be most likely to be a blade around 3'', surely won't be too cumbersome. Modern pistols are lighter, smaller, more complex and probably more fragile, not as suitable as bludgeon instruments compare to their flint shot ancestors.

I agree the Kabar design wasn't optimal, and as I said in the opening, the main drawback is it doesn't have a functional sheath, nor does it allows holstering. A small folder on the other hand will accommodate that. I do agree the closing retention can be a safety concern.
 

I have seen a few of these from the past. I assume they never caught up mostly because the lockup wasn't reliable. Also these are break action revolvers right? Then the blade may smack the user's hand during reload.
 
Imagine trying to stab someone with your trigger finger out of the guard. I'm sure that eventually it would find its way onto the trigger and BANG!!! You have better control using just a knife.

Never bring a gun to a knife fight.....wait...nevermind!
 
Yes, those are top breaks. Looks wise, they're my favorite of the folding bayonet concept, although it leaves some to be desired.

I think the concept could work, if the right design was chosen. In my eye, something like a modified slim liner lock would work best.
