How Slip Joints Work: Beginner Knife Knowledge

[@alanmarsden4422]

Hi everybody, I've got back into knive now at age 61, there's so many different types of locking systems it's amazing. When me and my older brother were kids we were given a pen knife each just before we went on our annual hills with Mum & Dad, that was it pen knife with 2 blades and would close on you if you put too much pressure on blade when cutting in wrong direction. Got a few cuts with mine so never bothered with it since as always thought they were dodgy. Then as I was getting older I remember our Government passing certain laws with knives cos of murders and basically idiots using them for other purposes other than intended. Just recently bought Opinel 8 &10 and love the locking system, lightweight and ok for what I need. Also, few years ago I bought a packet of jig saw blades which contained a pocket knife. I thought what the hell happened to the good old pen knife, it had a liner lock which is as I'm sure all you guys know a price of metal that springs out behind the blade when opened to prevent blade from closing, loved this cracking little knife until some scumbag stole it along with few other bit n prices. I emailed Wolfcraft in Germany and asked if they still made the jig saw blades with pocket knife, they said would have a check with stores dept. and sure enough they had en in stock. I was sent a packet free of charge and my knife is never far away from me now. Been feeling bit old and weary since hitting my 50s so loosing grip in fingers etc my little Wolfcraft pocket knife with liner lock helps massively with all those bloody plastic packets and other jobs. Thanks for reading and keep safe everyone

Thanks, that was just what I was looking for.

Great video.

[@jipvanleyenhorst4834]

thank you SO MUCH

[@timmatherly5080]

That back piece that keeps the blade open or closed is called a spring.

Thanks for the knowledge base. Is the Buck 110 a slip joint too?

[@MrDirtysteve75]

A buck 110 is a lockback knife. The blade is locked in place until you release it by pressing on the lever at the back of the knife.

[@petergoettler8680]

Interesting To Note! Thxs.,Merci.

[@MrDirtysteve75]

In Texas, there is only one slip joint and that's a Case Knife. We love em. We also love fixed blades, lockbacks, linerlocks. I'm going to have my Buck 110 converted to full auto.

Say Heah, Yeah, I have a few Slipjoint Pocket Knives, My Fav's is my Camillus Silver Sword, that's been used alot from cutting wire to whittling, even the Two Swords Etching is very light now. but what ever that stainless steel is, it holds a great edge and for a long time, Once I got it sharp all I do is strop it, so not alot of metal was ever taken off and it's in great condition, But I just got two Rough Riders, in the Moose Pattern the blades are tge same style as a Trapper, but tow blades on opposite side rather than side by side, the snap and the appearence is almost Case Knife quality, I find it hard to believe that a Company that would use that much care to male a knife so beautiful would skimp on the tempering, it's marked a 440, I know it's a 440a, but if tempered right, for a inexpensive knife, I would think they should hold up as a beater knife with some what decent edge retention, Do you have any experience with Rough Rider Knives as far as edge retention and what I can expect from their blades, Thanx in advance, , ,

Actually here in portugal slip joints are the way to go and are very used and we adapted them to our needs so most pocket knives are slipjoints just because they are simple cheap and practical and have less things that can go wrong

[@leebarker6188]

New sub thanks learned a lot

[@user-bs4jy9sr8m]

Loved the video, I was just wondering what holds the blade in place if you were to push down on it. In other words what prevents the blade from folding the other way towards you when force is being applied to the blade? Thanks :)

[@longviewstud26]

Thank you

[@theangel666100]

so essentially its a piece of metal that bends

[@johnnyjackson9852]

i cant understand how thick piece of metal(like in victorinox) can bend with that easiness

[@wompinator94]

A lot of it has to do not only with leverage but hardness, temper, and ductility of steel. That is to say, essentialy spring steel is not as hard as that steel used for a blade, it is made to have some "give" so it can bend a bit. Different types of steel have different properties and even the same kinds can have different properties depending on how they are manufactured. Hope this helps!

[@hphillips7425]

I have had knives like this for over 50years and never know what they were called

[@dfcvda]

its all we are allowed here in UK I had a UKPK

[@chrisblight6069]

Actually you can own other types of knife but can't carry them around in public, I believe that's the law here.

[@myrkur479]

Thanx for the video, so Cold Steel Kudu Lite 20KJ has this. Not buying the knife. Too sharp and dangerous to close on my hand.

[@danhaywood5696]

Anti lockback laws are crazy and dangerous to working people, especially those who often use folding knifes. It's law makers designing tools to purposely make them lame and thus unsafe. Cheap locks are unsafe also, but there's plenty of secure lockback designs. It's unbearable that silly ass lawmakers should be sabotaging working people's most basic tools. What's next, sponge hammers? Square steering wheels? How about blades with no handles? I remember as a US Navy sailor, I was required to ask permission for a fucking chit to carry my Buck 110, which I'd carried growing up. Yeah, I never complied with that shit. Remember one time at sea bringing aboard and stowing victuals aboard the aircraft carrier USS Ranger, I was the only man around with a fucking knife to cut straps and open big boxes, to distribute and stow. We were working in the Hanger Bay and a huge hatch was opened for getting stuff below, it may have had an elevator platform, I can't remember how we did it, but I remember working my ass off cutting shit free and evebody was calling for me or wanting my knife. Then a first class from somewhere, wattled over in our way, and demanded to see my chit. I told him I did play that game, and he started making big trouble for me, till the Chief in charge showed up bellowing about the clusterfuck, and was told it was because I had no knife chit. The chief was not very nice to the silly First Class ass. I was already back to work, and nothing was ever said to me about it. I carried that knife EDC everywhere for my entire enlistment without a goddamned chit. I had several encounters with asses demanding my chit, and always outright refused to respond basically. I can only remember that one in any detail. My take was: if your gonna take my basic tools, then I'm not gonna serve. Of course now days we got security BS everywhere watching us, detecting our tools, searching us, blaring at us, and entirely disenfranchising us in every basic manner. I feel like a goddamned puppet with an authoritarian hand up my ass. At least I can still own and use lockback knives where I live. Use the right tool for the job now days might get you riddled with bullets, or if you survive, they systemize you and kill your dog, make your family suffer, and steal anything of value you have while restricting your ability to ever earn a living again, while forceably educating you to realize it's all your own fault. Shit, I probably wouldn't use my knife if I was working now days, because the fuckers don't pay me enough to even be there, far less use my own tools and initiative. I've done it, just sat there with my knife in my pocket with everybody else who didn't have one, while zero work got done and our idiot employer looked for a working knife or box cutter. Same shit I should've done in the USN. Fuck them, just don't produce. Make the fuckers fill out paperwork to supply you with an unsafe legal turd tool, and then sue the motherfuckers when you get hurt.

a terrible artist but a Artist non the less =)

[@andrewkiaski6547]

I ABSOLUTELY HATE slip joint knives they may be the original but they have a jerky motion when closed and I have had one accidentally close on my fingers. they are practical but not for me

[@BigNorseWolf]

So long story short.. theres NO locking mechanism.
