Tolerances and Fake Knife News

[@BirdShotIV]

"I had to learn how to specify...car alarms." OK, listening to Elliott these days is a little like listening to Cliff Stamp, I am not wise enough yet to understand it all. Thanks for the post-it note example. Great video guys, and as always, MORE PLEASE! :D

BirdShot IV hey bird and frankie.....and pugs

The lock up on my Crux is rock solid when I work in the freezer. Which is -10 to 0 degrees Fahrenheit...

[@jclar3565]

It's interesting how much I have learned from my knife collecting over the years. From technical knowledge like this to knowledge about antiques, metals, sales, markets, history it even got me to delve into becoming a World War buff. Btw...the SR-71 was 107 or so ft long and grows in overall length at flight. I can't recall the exact figure.

[@EpicSnuggleBunny]

Painfully awkward, and dry, per usual. Enjoyed it! Would certainly enjoy more in depth, can't wait for you to blast the crazy amount of 'fake news/ misguided group think' about knife steels.

[@pipcorona]

It was not just understandable, but insightful. I very much enjoy the videos and the topics and information shared. Keep it up!

[@FW190D9]

Thanks guys. I enjoy Elliot’s “rants”, very informative.

[@thomassmith2056]

EPIC video and you guys are great!!! respect from Florida.

[@Kevinclearysharpstuff]

Great video thanks for doing this, I think most people understand what tolerances and specs are though maybe we watch different reviewers though. The explanation of what considerations go into determining tolerances was good.

[@rhahnabunaid]

Very informative! Thanks guys.

[@stevewelborn8744]

I'm nobody but THANK YOU for doing this video and look forward to more.

[@listenup455]

Nice explanations! The videos just keep getting better.

[@arie1293]

Very nicely explained.

[@DoctorFrunkey]

Awesome video. Thank you for sharing your experience and knowledge with the community!

[@kevinweaver4265]

Excellent Vid lads, very informative.

[@goodolecowboy13]

Videos are great! I don't mind the bit of the off topic rant but that's just me! Good team work guys haha.

Hmmm I’ve never had an issue with a ti framelock (unless it was due to hard use) and I’ve worked in a warehouse that stayed 20-32 degrees (dairy deli).. the warehouse I currently work in gets as hot as 100 or as cool as 40-50 degrees.. i keep a knife in my pocket at ALL times, from the time i get dressed to the time i go to sleep.. very interesting

While high end calipers measure to 0.0005”, they are only accurate to + - 0.001” to as much as + - 0.0015”. The manufacturers will specify that accuracy. So never use them when high accuracy is needed. Use a micrometer instead for thickness, diameter, etc. You can get them up to large sizes to 18” and beyond, in one inch intervals from 0-1”. They will measure to, and are accurate to 0.0001”. You have to remember something about accuracy. You need a measurement device that is at least five times as accurate as what you are measuring to have your measurement accurate to + - 20% of the least significant digit. So that means that if you want to measure to 0.001” you need your instrument accurate to at least 0.0002”. That way you know your measurement is never off by more than + - 0.0002”. If you use something accurate to 0.001” then your measurement can be off by + - 0.001”, and your result could be for 1”, anywhere from 0.998 to 1.002” that’s double your tolerance.

[@magicdave93]

Love your videos and this one is very interesting. Thanks for posting!!

[@yeaman992]

+FerrumForge Go down the rabbit hole of physics! Love the high detail and in depth videos! Maybe make something about blade geometry, grinds and blade thickness. Also something on production scale blade sharpening would be great!

[@SHADOW-ke6xz]

This was a great video guys very interesting

[@mattwyeth3156]

This is great

[@spyderg6509]

You guys are funny as hell and down to earth and you guys make some of the very best quality knives I watch your videos and find myself laughing my as off but you guys are geniuses making my opinion the baddest ass knives on the planet it’s so refreshing with the brains are in front of the camera explaining stuff myself don’t care to understand i love your knives it just shows you guys are not your average bears I subbed and cool as hell please keep this mentality cuz yes your videos are entertaining with engineering involved much props for being real to us consumers I live in Cali as well.👌

[@brocksdaddy081910]

Excellent video guys!!!

[@ScottieG59]

It sort of reminds me of milspec in firearms; the enduser gets parts that fit, despite the source.

[@cm42mejones64]

THIS video!!... I have some FF/WE/Massdrop knives, minus the Crux, and I joined the Buc drop but NOW I NEED a FF knife that only you guys have touched!... THIS video!!!

[@LutherDesigns]

Absolutely excellent video, thank you! Looking forward to more!!

[@dlangston2020]

Loved the insight. More Please. FYI, I take my Master Blaster snowboarding and it seems to work fine at Keystone an Vail with temps around 0-20 degrees....so nice tolerances! :-)

[@jimmyevans4795]

Keep em coming guys!

[@reinenruud390]

Awesome vid! Thanks for the in depth info

[@joec846]

Tight tolerance in that video maaaan👍😂

[@jeffcon123]

I missed the massdrop crux I want one so bad. Or make a affordable master blaster that was such a dope design

[@mikelikesknives428]

Great info. Nice explanations. I feel like an ass for using the tolerance term incorrectly. Thank you for the knowlege.

[@rflopes3]

Hello Guys. HOw do you darken your titanium handles ? It's DLC or some coating ?

[@lotriguitarist]

i wonder, with stonewashing, polishing and coating blades, as well as anodizing and sandblasting scales, how much does that throw off you measurements? and do you encounter for this as well?

[@tommyd3jr]

What is that knife in the background with the “Chaves lookin” clip? Pretty sure u guys did his midtechs* for awhile there but that doesn’t look like a Chaves

[@jamesbarisitz4794]

Sidebar- Can those leftover ti sheets behind you be recycled? It seems there's a ton of cash sitting around. I don't know if you are keeping it for smaller parts or no scrap yards will pay for it. Sorry to jump off here, but it stuck in my mind.✌ .

[@christamu2]

Great video. Are you using GD&T in your drawings to handle critical hole locations, concentricity, scale flatness, etc? Always interesting to see how other industries and makers deal with this.

[@madman94]

Great vid, keep the topics coming, the world needs more ferrum forge content!! I also need more sm100 blades from you guys 😉

[@thomassmith2056]

"I like cutting stuff, mostly cheesecake"😁lol

[@MrLiamCooley]

Limits ans fits

[@georgeshaw8925]

Elliott can you find me a sm100 stinger

[@yartar-pq9yp]

just bought the massdrop buc

[@kenfair8178]

My head hurts.... but in a good way. Sounds like a lot of trial and error before you gained the knowledge of just how much tolerance you can even plan for/accept that will actually work and how minimal gaps you can design in.

[@kenfair8178]

Also CHEESECAKE!!

[@dalogg2]

...and don’t stack tolerances

[@swiggamortis5521]

If only those boys were intelligent 😜

[@keithwilliams5151]

Nife Nerds!!!!! Wait, yeah thats correct... lol
