Knife How To; Spring Assisted Knife Storage

[USNSarDiver]

Wat knife is that

[Pimpzilla300]

My sog Tridents coil spring broke yet the assist still works. Wonderful.

[sirhorsechoker]

Physics metal fatigue. I was told cycling a spring wears it down. So playing with the knife ages it. Not so much as long as the spring is not in motion, even if its under tention. I could be wrong. But you see magazine springs from old soviet countries, they are like new, even though they sat, in tention, for decades bfor you bought them.

[scoobydoo6906]

@sirhorsechoker I totally agree. the spring cycling causes the wear. A good way to understand this is take a plastic knife flex it a bit and hold it there. hold it for a long long time. did that knife break? nope. now start flexing it. guess what's going happen? it's going to break. I am not saying being under tension is not very very slowly breaking down springs. I am saying opening it to store the knife is probably hurting the spring more, unless you are storing it for like a hundred years.

where would you find the smith and weston that he showed

[Jon38]

Thumbs up for TootenFart being the "Funniest YouTube Name Ever"!!! LOL  ;P

[keylitho]

I have had my Original Benchmade AFO for 10+ years... never stored open and still work's like the day I got it..

[evilsquirrel56231]

That knife looks like a Kershaw Junkyard Dog knockoff... Good vid, learned something today

[tokke509905]

What do you think is the best 15-25 $ knive?



[knifelover1225]

what knife is that?

[bennor3]

i am amazed at your ability to say tootenfart without smiling.

[johnjjbjohn]

Will you make a video talking about the legality involved in automatic and balusong knives? Please go in to detail with laws, consequences, and likelihood of actually getting into trouble with the law, provided that you aren't starting any. Thanks!

[zanuha]

@johnjjbjohn

State laws -.-

[jhoops924]

@phb2409 yes thats correct, the only way to break the spring is to stretch/compress it passed its elastic limit, then the spring loses shape and doesnt work but as long as the knife was made correctly (which im sure it was) then ther is no problem

[PavlovSandor]

oh boy. tootnfart!!! hmm. which do you like better. coil springs or torsion bars. ive had a few torsion bar failures. where the bar just snapped or bent in the wrong spot.

[enriquesonora1500]

LIked this video. It is the obvious and simple things we overlook that can bring a lot of value to our lives. Thanks

[tootenfart]

Thanks for the help, and sorry for the name I made this account when I was like 8 beacause I wanted to comment on videos.

[eulbsvder]

@tootenfart so your like 10 now? thats what your channel says, haha but whatever, it was actually a good question

[MrScrubbys]

@tootenfart LOL your name makes me lol

[EdmontonOpTic]

Can you give me an idea of a good secure display case for a home? Im starting a collection and id like some ideas.

[timmit104]

Duct tape: A MAN'S BAND-AID.

Did you cut yourself on the job??

[96devin96]

what is a good way to store a out the front knife?

[slimnskinny]

Great vid :D uhmm a question let seee uhhm: Can blades be ruined by sharpening a knife. I dont know how to sharpen knifes yet and the only knife i own is the spyderco delica. I want to sharpen it but idk how D:

[RyanMatthewHill]

@slimnskinny not unless ur a careless dumb ass... bye a soft-stone, or go to the smith's abrasives website and buy the yellow one, idk the name but it has two sides, and i have one from walmart.. its arguably the best sharpener ever (in my opinion)

[geardog32]

I agree, Its the same with your gun magazines. When left loaded for a long time (years) the spring with not rebound with the same force it used to, requiring new springs.

[nofgood4live]

if i had a spring asisted knife,i will store it open.

also switsh blades.

but out the front (otf) i dont know??

[Spherical3]

I'd like to see how to remove rust from a blade and keep it from coming back. My Kershaw Leek recently started to show a fair number of spots and it doesn't exactly look pretty.

[PRSpl4yer]

BM Nitrous assist doesn't need to be stored closed due to the nature of the Ti assist torsion bars.

[phb2409]

I'm no knife expert but I know a little about physics... I was under the impression a spring can store that energy indefinitely, and as long as it's not stretched in the wrong direction, or past its limits, it will continue to function perfectly. A spring stores elastic potential energy, and that energy - any energy - can't be destroyed.

[FutureMarine246]

@phb2409 hmmm, well the energy wouldnt be destroyed just transfered into another form

[DarkStar851]

@phb2409 The physics of elastic energy stored in a spring are certainly solid, but there are tolerances with other handle materials in some cases that can eventually experience wear. Some handles can't keep up to the tension expressed from holding back the detent after (MANY MANY) years of time. The physics still make sense, it's just something largely overseen.

[phb2409]

@DarkStar851 Ah that would make sense, I never thought about the other components of the knife.

[TheMHandDSfan]

@phb2409 Really? I thought that a spring would loosen over time if it consistantly holds all that energy? I'm probably wrong but I feel like i should get a better feel of whats going on.

[phb2409]

@TheMHandDSfan No, I mean it is possible to push a spring past its limits and break it, but within those limits it's capable of storing energy indefinitely. DarkStar851 made a good point though - other components of the knife may not be as strong, and may weaken because of all the tension in the spring. So the spring should always stay strong, but other parts may not.

[TheMHandDSfan]

@phb2409 oh ok i see what you're saying now

[schopenhauer1962]

@phb2409 Physics is mostly theoretical, you know , ideal circumstances. So if they say 'spring' they think of an ideal spring. The problem is that there is a huge diference between mathematical physics and engineering of a knife. On earth we have gravity, air resistence and metal fatigue...

[13mschen]

@phb2409 I was under the impression that a spring will lose its tension over time by slowly emitting the stored energy in the form of heat while the spring reshapes itself to fit the new environment. however i could be completely wrong.

[DeagleBeagle]

@phb2409 no you are wrong, if you have a constant force pushing on the spring from being closed, it pushes the spring in the opposite way the spring wants to go. Eventually the spring's pushing back force will decrease, as the spring becomes weaker over time. The time it takes for most knives is very very slowly but it will wear slower if you have the spring in its extended position.

[FoldingKnifeFanatic]

i've been wondering about this..thank you

[MrRRSP]

nice tutorial

[redpanda412]

I didn't know that. Thanks. When are you gonna Do another contest

[richman587]

SECOND....bitch...



[lnt871996]

@richman587 actually third

[richman587]

@lnt871996 fuck....



[anasianguy09]

is that a assisted version of the junkyard dog by kershaw

[Nurple17]

@anasianguy09 Nope. It's a different knife. If it was a Kershaw, he would've said so.
