Russian engineering!!!! When I first got my Mosin Nagant, I was trying to looking for a tool or something to disassemble the gun. And turns out, the tool to disassemble the gun is the bolt... Russians know how to make a stuff with minimum materials..

Bolt actions are one thing, but when it comes to modern rifles, the AK and AR platforms are spot on. A lot of over engineered shit has come and gone while those two remain King of the hill
VERY informative! This was an excellent video. Due to watching your video, I have selected this knife as being my go-to survival knife. You have proven its functionality, and it will do everything I need it to do. That is one very thought out very strong knife. Thank you for your demonstrations & helping me make my decision.
The plastic in the sheath is to protect you from electric shock if you need to cut electric wires in the field. It also stops the sheath from making a clanking sound when you need to be quiet.

I have one of these my father gave me. He got it during Desert Storm. An Iraqi soldier had taken his underwear off, and tied it to his rifle, waving it over his head, along with dozens of others doing the same. It is how they surrendered. The weapons were confiscated, and all of the bayonets ended up as war trophies. I actually have 2 of them.
Have 3 of these so far. One Romanian, one Bulgarian, and the pride of my collection, my authentic Izhmash produced Russian bayonet that bears the famous arrow in triangle on the sheath and the top of the grip. A knife just as reliable as the gun it's attached to.
Hello im from Serbia (ex Yugoslavia), you can use that bayonet as a hammer by putting the ring in the scabbard of the blade, and use the scabbard as a handle. You just must be careful not to hit your self with the blade when you hammering.
You should start doing more "How to make" videos again, they were really great, and i have done them all. If you would allow a little suggestion, you should try making a bulletproof vest. They are fairly easy to make, but a great thing for SHTF/Survival.
Putting a pipe over the sheath or the handle when using it for wire cutters will give you more power (same idea when changing a tire- put it right over the tire iron & you can put a lot more muscle & weight behind it in a safer way).
The blade in not bolted to the handle...you can simply remove it by pushing out the cylindrical plastic piece in the center of the handle...Greetings from Yugoslavia!
Laglemamu'g Gjiga'qaquj Why not have a Leatherman in your pocket & a small Swiss Army Knife on your keychain? That way, you at least have a good pair of tweezers.
I carry a Leatherman wave on my hip everyday it's super handy and I can't believe how I could have lived without it. If you get the EOD black coating it will leave some extra so you need to wipe it down once you get it or yours hands turn black but once a the extra is cleaned off from manufacturing it's perfect and doesn't come off at all. Not even the saw blade has lost its coating and I have been using it heavily over the last few days. Also it will be slightly thought from the coating but if you get the regular silver I don't think you will have any problems what so ever. I also have the molle sheath and it works great. It has a pocket inside so you can get the extra bit set if you want.
I have a unused Soviet bayonet in brown/orange plastic in mint condition. And a Yugoslavian near mint condition. I am ethnic russian myself so proud to have them in my collection. 🇷🇺🇸🇪
The steel end cap is actually made for hammering. On the type 1 bayonet you just had a round end of the grip, so when soldiers used it as a hammer they broke the grip of their bayonet, that's why they added the steel end cap on the type 2. Also, since both parts of the wire cutter are not isolated, it will produce a bright flash and a short circuit that could melt away parts of the bayonet if you cut an electrified fence with one positive and one neutral wire. I read about this in a NATO-manual some time ago, but i did not try this with my own AK-bayonet, so i cannot confirm it.
People often forget that spears are the most versatile melee weapons. They require very little technique, and offer great range. The only reason people stopped using them is because feudalism changed standard battles into sieges.
Not a bad multipurpose blade, it would be handy to have if your going on a camping trip or your going on a long hike just in case things go wrong.

I just got one of these and I’m looking for what the hook in the spine side of the guard is for, If anyone knows please respond to this comment, I’d love to know
It's funny how Americans actually copied the Soviet design when it comes to bayonets. The M9 bayonet has all the same features, albeit bigger and more Rambo-ish.
PMC I agree. It's just funny how the American armed forces are always portrayed as the superior force in every way, yet they quietly and thoroughly copied many elemental things, like the bayonet, from the "backwards and underfunded" Soviets.
MrAspentree thats because the soviets worked in different ways. In America, a company comes up with an idea and tries to sell it to the army. This can be a great advantage or disadvantage, because its out of the box thinking. the product might be a huge innovation or a glorified paperweight. Soviet tech is designed based on basic needs and most cost effective. a study is done to find what a tool needs to do, and how much it should the cheapest product that meets the most requirements is chosen. both systems have their merits, but the american system lends it self to "ripping off" and "copying" of ideas more than the soviet.
When you "holster" the bayonet, which side of the blade is supposed to go onto the bottle opener side? (I want to know do I have mine the correct or the wrong way)
The bayonet scabbard also fits into the side of the front sight assembly on my Romanian WASR, and the "bottle opener" part hooks on to the upper part -- I'm assuming as some kind of adjustment wrench.
Had to get a wetstone grinder to sharpen this. The steel is tough as nails. It's annoying to get the knife in and out of the sheath since the spring, that holds the knife in, gladly dulls the edge. This knife is a tank!
the round part between ga dle and knife is not just to go over the barrel, cuz ither wise they just not out it there..its puspose is to be use as an anchor ,attach a rope thro it throw it and it will catch and anchor itself
The blade is not full tang, or at least it is not on original bayonets, so you can cut wires with electrical current in it. note that also the sheat is insulated by plastic.
Slaughter round The G-36 Bayonet is actually surplus East-German AK bayonet that the barrel ring was taken off with a new one welded on, and some other mods for it to fit on the G-36
+Sam Drysdale because the left is horrified of bayonets. That's the reason that people have paid $100 to gunsmiths to weld-up and remake lugs back on their rifle; which were removed off for import. Mine has the lug and I have a bayonet for no real reason really. The same goes for suppressors. Those are not obsolete like bayonets, but since liberals tried to ban them - they have become more popular. Before Clinton's ban, you didn't see all the scary looking suppressors with teeth on them and shit. I don't like those, but I have to admit, I want a modern vortex flash suppressor and liberals not wanting me to have it, makes it easier to over-spend getting one, just like wasting $20 +shipping on a bayonet.

Has anyone figured out what the little hook shaped thing at the end of the hilt/handguard is? It's right behind the saw part of the blade if anyone sees what Im talking about. Not entirely sure what that does. Also I figured the saw could be used to maybe make shaving for starting a fire.
Flintlock rifles could shout 3 bullets per minute and there were techniques to shoot two more bullets within that 3 bullets in 1 minute range but I think that was all you could do. Though I he talked about stuff mostly about the 1600s and I don't know much about guns during that time.
Hey Kgbsurvivalist, I just got one of these bayonets and it is rather dull but is effective. However I would like it to be sharper for finer work. I have tried multiple sharpeners and have had very little success. How would you suggest sharpening it?

Loremaster Yn'Taris the South African R-4/R-5 assault rifle bayonet also had a bottle opener. (I think that the South African rifle was based on the Galil).
can someone tell my where my akm type 1 bayonet comes from? its black not wood looking like a russian one (plastic). it has a gray leather thing to put it on your belt and a brown rope around the holding area (bad English pls understand, its so you dont lose the knife during a fight if you are swinging it) i thought of east germany or poland. but they are a bit different.

the first bayonets were essentially barrel plugs you'd plug it down the end of the bore and voila you've a spear

My East German AKM bayonet came in today. Looks REAL used, however, this guy is TOUGH and shows its German craftsmanship. I really like it.
People often forget that spears are the most versatile melee weapons. They require very little technique, and offer great range. The only reason people stopped using them is because feudalism changed standard battles into sieges.
Seems the Soviets were ahead of us here. We designed our own m9 bayonet in the late 80s. And those apparently had problems in the initial batch.

Very good. Can you share where you got that Yugo for $20? That is a great price for a great bayonet.

The First gunners had to be protected by pikemen. So the pike on the gun was an obvious evolution.
Love the practical application section. If I need to assault a paint can I know that I am ready! PS, the cat...

I wish these where still $9
Would this fit on the regular stock muzzle brake ???
What he didnt mention is that steel quality is not so good. It is very brittle, standing on these is a good way to fall. But for only 9 dollaz?
Its an army knife ... it held me when i stood on it (70 kg) so yes its awesome. And the price does not say how good the knife is...
Put the Ring of the knife inte the Scabart, and you have a hammer or small picke axe.
What's the name of this knife and where can I buy the exact knife?
can someone tell my where my akm type 1 bayonet comes from?
its black not wood looking like a russian one (plastic). it has a gray leather thing to put it on your belt and a brown rope around the holding area (bad English pls understand, its so you dont lose the knife during a fight if you are swinging it)
i thought of east germany or poland. but they are a bit different.
I have one like that but it's a collectors knife because it's for Chinese AK-47 when anyone could produce Ak's
Best knife
nice. what steel that knife is made? tks
CS GO needs this type of Bayonet
6X4 bayonet 1965-1985 :)
Really? Is that when the Yugo type ii was made? I cant find very much any information on these.
